Ok, short intro as I'm new to the this forum (and forums in general).

I'm 34, been playing golf since I was a child but stopped for a while and started again about 4 years ago. As I'm starting to take the game more seriously I thought I'd treat myself to a fitting session for a new iron set ... and I'm now more confused than ever.

Although I recently broke 80 (+8) for the first time, I'm usually in the mid-high teens over par and, unlike most of my playing partners, my short game is very good while my longer irons don't go far and my driving is comfortably the worst part of my game. As I'm 5'7", I assumed the fitting session would be recommending shorter shafts but the 'advice' turned out very different than I expected.

The fitting session highlighted that my biggest problem was my distance and that was because I have a very high trajectory with my irons, he identified the weakness in my swing at impact, and that is something I intend to work on. I was very keen on getting some Ping irons as they felt the most 'balanced' to me and I also preferred the way the i20's looked at address. He tried to steer me away from these though as he said the lofts weren't right for my trajectory? is this right, surely if I'm going to work on improving the way I impact the ball this should not be a factor?

Secondly, I've always struggled hitting my longer irons and when checking the lie angle, he suggested going for 3 degrees flat. This made sense to me for my longer irons as the toe does sit up a lot, but not so much with 8,9,PW as they don't seem so bad and I hit them well. Also, almost everyone I see getting fitted has to go for more upright lie angles and other advice I read online said that flatter lie angles result in fading the ball (which I already do with my standard off-the-shelf clubs, I don't want this to turn into a slice!). Should I be considering getting different lie angles for 4,5,6,7 than I do for 8,9,PW ... or is this tinkering too much?

Finally, the fitter didn't think I needed any changes to the shafts (regular length, regular steel) even though I had a relatively slow swing speed of 78-80mph. He did recommend a slightly smaller Aqua grip though. Does this all sound normal to you you guys or should I get a second opinion?

I went in thinking I had a good swing and a reasonably strong game in general, and left feeling terrible lol. He did I say I swing the club well but now I'm not so sure. Obviously I want to improve but hitting high approach shots into greens and stopping them has always been the best part of my game and I don't want to lose that.

Any advice appreciated.

I see two options:

1. Get fit for the swing you have. Flat lie, lower launching heads... And improve your game because the new clubs fit your swing. Any swing compensations that you have now, will remain as the new clubs will allow and encourage the current swing.

2. Get fit for the swing you want with your body measurements. This option will encourage you to learn the swing you want because the clubs will perform best when hit correctly.

I like option 2 for anyone who is working on their swing. For my Dad, and many others in their 70's, option 1 is the way to go.

Thank you for your input, the fitter I saw seemed to be advising option #1 despite me saying I was willing to work at my problems.

My outstanding concern is about having different lies for different clubs. I still feel I hit my low irons well (certainly get the results I want anyway) so don't want to make too many changes to those. I do feel that having a flatter lie in my longer irons would help though.

Is it ok to have half your irons set at one lie and the others at a different setting? or is that something I should overcome with a decent coach?

That's kinda crap statement there. Because irons are built as a set. They have standard club length differentials and loft differentials that make each club have about a 10-12 yard gap between iron shots. So, it doesn't matter what the lofts are for your swing. When you need to concern yourself with is getting your hands forward at impact with a flat left wrist at impact.

What matters more is the shafts, which will load differently. So you want to find a golf shaft that loads correctly for your swing. So lets say your hitting iron shots with your hands forward, flat left wrist, weight on your front foot, and the height is still way to high, lets say 120 feet in the air at apex. Then you'd probably need to look at the golf shaft, get something with a higher kick point to get that trajectory down.

As for grips, depends on what your looking for. I like golf pride, they are a bit more tacky than winn grips which i like. I bounce around from midsize grip with little build up tape, to standard grip with more build up tape. I think i am going back to standard with more build up tape here soon. I think midsize is just a tad to big for my taste. But, some people like larger grips, some like smaller grips. The general rule of thumb is that your last three fingers on your left hand don't dig into your palm when you grip the club.

I would worry about a club fitter telling you about your swing. I seperate the two sides because it sounds like hes' trying to make up excuses for you to buy equiptment, making it seem like you need it to improve your game.

If you mean different from standard, then I'd say it is odd. Something happening in your address position that changes your swing more than most from short to long irons.

Each club in a set has its own lie and when you go more upright or more flat, you change every club from its standard lie the same amount. e.g. one degree flat changes each club by one degree but does not make your 5-iron lie the same as your 9-iron.

Perhaps a lesson that would focus on address and setup would also give you proper club specs for the address and setup you want to have.

Thank you both for your thoughts. I thought it odd that the fitter didn't even consider giving me different shafts to try, he said my club head speed was very slow (averaged at about 80mph) but that it was something I could improve through coaching. I should have stated that the fitter was also a club pro as well though.

I'm definitely going to get some lessons as the point about my wrists at impact is correct (and to be fair to the fitter he did identify that). I've also booked myself in for a second fitting with a different fitter though just to see if the results come out similar.

Overall I think I'll be going into my second fitting with a lot more insight as to what should be going on. Nobody has raised concerns about the 3 degrees flat suggestion, so I'm assuming that isn't a major problem. I am pretty much sold on the Ping i20s though so I hope it all works out!

Thanks agin to both of you for your input, I'll be sticking around on this forum!

How tall are you and what is your wrist to floor measurement?

3* flat is very flat. And some flat and others not is odd.

Since you like the i20, be aware that Ping set the standard for measuring lie angle on clubs, and sending you the correct lie angle from the factory. The color code dot on the iron head identifies the lie angle; Ping uses wrist to floor as a rough starting point on lie angle, but you actually have to hit some shots on a lie board to get the right angle. Your stance and hand position also influence what lie angle you need.

(Caution: don't let a fitter tell you that because you have wrist-to-floor X , that you need a lie angle Y. Hit some shots to see what you need; w-t-f is only a starting point).

Have you hit the i20's on the range? I don't know what clubs you use now, but I noticed that they lowered my ball flight a good bit when I tried them at a demo day. I would also hit some balls with a 3* flat Ping iron to make sure you are comfortable with that before you jump at the purchase. Like someone else said, that is a pretty big jump from standard.

When I was hitting the standard club off the lie board, the markings were well off centre towards the heel of the club.

The fitter switched me to a 2 degrees flat club and the markings were still slightly off centre towards the heel, so he suggested putting me down for 3 degrees flat, despite them having nothing flatter than 2 degrees for me to actually hit. That's part of the reason I want to go back for a second fitting, as I thought this was a bit too much like 'guesswork'.

My next fitting is on Wednesday, I'll update this with however I get on.

Tough to say, lie really wont effect your ball flight much if its with in a few degrees of were it should be. The math supports this fact, and Erik has done a good video on why, but basically because the loft makes the oblique angle change caused by lie to be vertical than horizontal. So irons with much higher lofts than putters and drivers, will not be effected by small lie changes.

not an expert at all but i did read stan utley's book on the short game and he said that he had the lie angle of his wedges made flatter (vs the rest of his set) bcoz the standard miss with a wedge is a pull / hook, while the standard miss with a longer iron is a push / slice (which a more upright lie angle would help cure).  so to answer your question re having "different lies for different clubs" - probably a yes - to having different lie angles for your long vs short irons.

I can see this happening because a lot of people choke down on the club, which makes the club more upright.

You can get clubs that fit to your swing or fit to your body and then develop a swing. You decide if your dynamic fitting (hitting a board and all) is right for you. It is NOT right for me. I know what swing I want and and I get fit for that swing, not the swing I have in the shop the day of my fitting.

rusty,

I agree with what you say, but would like to expand on it. Advice from GolfWorks is that the lie-angle measurements of a person's golf swing stabilize quickly and are fairly constant*. So, the lie board is often included in static fittings , although it is technically a dynamic measurement.

Also, whether you get a new set from the factory, or buy a used set, ask the club shop fitter to do a loft and lie check on the irons to make sure they meet factory specs (as adjusted for you in fitting).

-----------------------------------------

*constant: (This assumes a person does not make a major stance or swing adjustment. A few years back. I went from 2* flat to even, because I quit crouching so much in my stance).

I hear you, and believe you that GolfWorks says it is constant, but I don't believe that is true.

I don't think distance from the ball and ball position are constant for most of us over 5 in handicap. I know from experience that if I don't check my ball position, foot spread, and distance to the ball while on the range, it will differ from my perfect setup. If my set up is not perfect, and I still hit the ball, something will have changed in my path and/or plane at impact. So, it seems unlikely that my lie would test the same from day to day even if I was trying to keep it the same. So the day I get tested, would be the day I learn to consider correct. And I'd create any needed swing compensations to flight the ball well. This is a slippery road toward inconsistent results.

I'll stick with my pro's recommendation based on my measurements.

BTW, I do get my lies checked because beating on the range can bend them. And, "standard" lie can differ between sets. Over time, manufacture's standards have often become more upright.

Agree with saevel above that this doesn't make any sense.  The lofts of the clubs are only relative to each other, for one, and further, i20 lofts are right in line with a lot of clubs nowadays in their standards.  If he said the clubheads weren't right for you because they are designed to launch it high that would be one thing, but the lofts comment is goofy.

There isn't really a "setting" for lie angle.  Just like loft, to some degree (no pun intended), and length as well, all manufacturers have a different "standard" as their lie angle.  In looking at my club specs (custom fitted) versus i20 standards, I guess the answer to your first question is yes, lol.

Standard i20 lies start at 60 for the 4 iron, and then get steeper by increments of .75, .75, .75, .75, .75, .25, 0, .25, .25.

My set starts at 63, then gets steeper by increments of .5, .5, .5, .5, .5, .5, 0, 0, 0.

Know what you mean. Each manufacturer has slightly different standards as to what they count as an "average" lie angle. When I put sole tape on Ping irons, I usually get recommended to go .75* flat . For Callaway, I get recommended for standard lie.

    • Nah, man. People have been testing clubs like this for decades at this point. Even 35 years. @M2R, are you AskGolfNut? If you're not, you seem to have fully bought into the cult or something. So many links to so many videos… Here's an issue, too: - A drop of 0.06 is a drop with a 90 MPH 7I having a ball speed of 117 and dropping it to 111.6, which is going to be nearly 15 yards, which is far more than what a "3% distance loss" indicates (and is even more than a 4.6% distance loss). - You're okay using a percentage with small numbers and saying "they're close" and "1.3 to 1.24 is only 4.6%," but then you excuse the massive 53% difference that going from 3% to 4.6% represents. That's a hell of an error! - That guy in the Elite video is swinging his 7I at 70 MPH. C'mon. My 5' tall daughter swings hers faster than that.
    • Yea but that is sort of my quandary, I sometimes see posts where people causally say this club is more forgiving, a little more forgiving, less forgiving, ad nauseum. But what the heck are they really quantifying? The proclamation of something as fact is not authoritative, even less so as I don't know what the basis for that statement is. For my entire golfing experience, I thought of forgiveness as how much distance front to back is lost hitting the face in non-optimal locations. Anything right or left is on me and delivery issues. But I also have to clarify that my experience is only with irons, I never got to the point of having any confidence or consistency with anything longer. I feel that is rather the point, as much as possible, to quantify the losses by trying to eliminate all the variables except the one you want to investigate. Or, I feel like we agree. Compared to the variables introduced by a golfer's delivery and the variables introduced by lie conditions, the losses from missing the optimal strike location might be so small as to almost be noise over a larger area than a pea.  In which case it seems that your objection is that the 0-3% area is being depicted as too large. Which I will address below. For statements that is absurd and true 100% sweet spot is tiny for all clubs. You will need to provide some objective data to back that up and also define what true 100% sweet spot is. If you mean the area where there are 0 losses, then yes. While true, I do not feel like a not practical or useful definition for what I would like to know. For strikes on irons away from the optimal location "in measurable and quantifiable results how many yards, or feet, does that translate into?"   In my opinion it ok to be dubious but I feel like we need people attempting this sort of data driven investigation. Even if they are wrong in some things at least they are moving the discussion forward. And he has been changing the maps and the way data is interpreted along the way. So, he admits to some of the ideas he started with as being wrong. It is not like we all have not been in that situation 😄 And in any case to proceed forward I feel will require supporting or refuting data. To which as I stated above, I do not have any experience in drivers so I cannot comment on that. But I would like to comment on irons as far as these heat maps. In a video by Elite Performance Golf Studios - The TRUTH About Forgiveness! Game Improvement vs Blade vs Players Distance SLOW SWING SPEED! and going back to ~12:50 will show the reference data for the Pro 241. I can use that to check AskGolfNut's heat map for the Pro 241: a 16mm heel, 5mm low produced a loss of efficiency from 1.3 down to 1.24 or ~4.6%. Looking at AskGolfNut's heatmap it predicts a loss of 3%. Is that good or bad? I do not know but given the possible variations I am going to say it is ok. That location is very close to where the head map goes to 4%, these are very small numbers, and rounding could be playing some part. But for sure I am going to say it is not absurd. Looking at one data point is absurd, but I am not going to spend time on more because IME people who are interested will do their own research and those not interested cannot be persuaded by any amount of data. However, the overall conclusion that I got from that video was that between the three clubs there is a difference in distance forgiveness, but it is not very much. Without some robot testing or something similar the human element in the testing makes it difficult to say is it 1 yard, or 2, or 3?
