same length golf club

Recommended Posts

Does any one have tried or been using the same length club- 1iron golf is the most popular one, it seems like. It makes sense from theory but the fact that not many people are using is discouraging. Basically these irons have the same length/lie(usually that of a short iron depending on your wrist to floor measure) but different loft.

The main claim is that the distance increase due to the length difference is only fraction compared to the loft difference. These people claim that a 3 iron that's the same length as 8 or 9 iron can hit as long as regular length using these. But since it is shorter, you can hit more easily. If you want to get more info, just google 1iron golf.

longer club = more club speed.

Yes that's correct. But it's matter of how much more. Newton's law says, given the same amount of angular velocity(i.e. swing tempo) the linear velocity of club head is directly proportional to length of the arc( club length). If your shoulder to club head length is 70" for a 8iron, than 4 iron would have 72" shoulder to club length. The difference is about 3%. That means the club head speed will increase by only 3%.

This may be a little bit of over simplification since golf swing is more of double pendulum motion but the distance gap among the different clubs is mostly due to the loft. I remember Anthony Kim's interview about his habit of choking down on clubs and he said that by doing so he loses a little bit of distance but gets much more control.

That would be 5-8 yards for typical golfers.

I have a set of them, although, I switched out the shafts that come with them and put on the grips I'm used to. It took about a month to get used to having them be all the same length, but now I really like them and my iron play is much more consistent.

Loft for loft, I get about the same distance as I did with any of my other conventional iron sets.

I wrote a review about my experience with them. I don't know if the forum admin's would want me posting the link, so if you'd like to read it...just send me a private message.

I'm not an Admin but I can't see why they would stop you posting the link? I'd definetly be intereseted in reading your review.

Okay. Here is the review link.

http://www.swingmangolf.com/1ironGol...lubsReview.asp

The only two companies that I'm aware of that currently make same length clubs are 1iron Golf and Pure Fit Golf.

I've never tried the Pure Fit ones, but I do have a set of the 1irons. I like that the Pure Fit's are forged and you can bend them, have adjustable weight ports for length and swing weight adjustments, and have a progressive bounce...but mostly I went with the 1irons because I could get a whole iron set, the offset was the same between the clubs, plus they had a money back guarantee.

I swapped out the shafts that came with my 1irons for some Dynamic Gold SL-X100s, spine alined them, and put in some Sensicore. Distance-wise, I get the about the same yardages when I compare loft to loft. Length of a club plays a minor role in distance like some people have mentioned, but loft is the primary determinant. Any distance I lost with the long irons, I think I made up for in better contact. It was funny with the longer wedges at first too, but now I'm used to them and really like them that way because of the consistency in setup and swing from club to club.

I'd eventually like to experiment with the iMatch's...just haven't done it yet. In either case, I don't think I could go back to a conventional set again. :-p

Okay. Here is the review link.

Interesting article. Thanks for posting. I checked some of the Pure Fit dealers that they list, but can't find the IMATCH product on any of them. Must not be a big seller.

Tommy Armour used to make a set of irons that were all the length of a 6 iron. Miserable sales success. The short irons were harder to hit accurately, and the long irons were still subject to a lot of the same physics (lack of loft means not as much backspin which means the sidespin has more impact) as regular clubs, but with a loss of distance. Basically, one got the worst of all worlds.

There's a reason that over a hundred years of golf club evolution has settled on sets with graduated length differences.

Yup, glad to help.

FYI, I got an email from Tim Hewitt, one of the iMatch dealers...apparently they are sold out at the moment. Every time they do another run at the foundry they use, I think they have to commit to 500 sets. So like a lot of companies they are just waiting for the economy to improve a bit before making more.

Do you know the specs on the old Tommy Armours? Even though they were same length clubs, maybe there was something objectively in their design that weren't making them sell well.

Well the science makes sense. Assume a half inch increment between length of each irons, so from 4-pw it's a difference in length of 3 inches. Well, check the calculations with a driver which has more length and more CHS speed. A very simplified equation where you can assume the lengthened shaft will have the same weight and could be swung with the same rotational speed will show that adding 3 inches to a 46" driver would THEORETICALLY give a 120 mph swing, a bump up to 127.78 mph. NOw that's very simplified and assumes a ton.... but for a driver that's not an insignificant increase, but not necesarrily worth losing all control over either.

Irons are dealing with lower club head speeds, but also shorter shafts, so a 3" difference from 4-pw is a higher percentage than it would be in a driver. A typical 38" 4 iron that was the same length as a PW would be 7.89% shorter, so a 90 mph swing would be roughly 82.9 mph.... which is fairly undesirable. HOWEVER, I think this system would be beneficial if you just made everything the same length as maybe a 7 iron, because then the difference in 4-7 and 7-pw would be 2" or less, so a smaller percentage lost or gained in CHS? I have trouble hitting really low clubs like SW and LW often anyways because I feel a little too squated with the short length, so this is a pretty cool idea.

What this would do though is give more consistent yardage transitions from iron to iron. For instance, somebody now may have just an 8 yard distance from PW to 9....but near 20+ yard distance or so from 4-5... bringing up some challenging choices on in between distances. This would likely keep all club yardages in smooth increments, which could be good and bad, but I think mostly good, especially for golfers who aren't single handicappers.

Few things to mention here ...

(1) The weight of the club head is never mentioned in these discussions. The 3-iron in the 1-iron golf set is shorter in shaft length than in a standard set, and yes the clubhead speed is a bit less than the clubhead speed in a standard set because of this shorter shaft ... but the force exerted on the ball is not just a function of clubhead speed. The mass of the 3-iron head in the 1-iron set is significantly more than the standard, so the force on the ball is almost identical for a perfect hit.

(2) Loft. The lofts in the 1-iron set are in 4 degree increments throughout the set. The lofts in a standard set are not, for example most 3-irons are only 3 degrees stronger than the 4-iron.

(3) You hit the centre more on shorter shafted clubs. This one is always held up, and it's true. No-one mentions the fact that the reverse applies to your 8,9,PW etc... that is, they are longer in the shaft than a standard set - and should be therefore harder to hit. The combating argument talks about the huge benefit of having only one setup. I agree with full shots that this applies - but with the wedges it just didnt play out that way in real life.

I used the 1-irons, and they were awesome. Very consistent, very confidence inducing. I only ended up using 3-iron to 9-iron at 37 inches - with my own spined shafts. My wedges were all Clevelands (46,50,54,58) at 35.5 inches to MOI match.

The distance gaps inbetween irons was as even as a standard set, if not better ... but the ball flight on the 3-iron was definitely lower with the 1-irons, and stronger than normal (which I liked). Same goes for the wedges ... before I changed my make-up I would hit the PW, SW, GW, LW very very high.

Overall I loved them. Best set I have built/used by miles. Helped my scoring through confidence and consistency.

I am speaking past tense because I have had a self-prescribed break from golf, and have not played in a while :)

    • Clearly it's a lot of both, but I've always wondered that if golf is such a mental game, why do players only seem to practice the physical side.  And how does one even practice the mental side?  I've known a few players, not that many, who didn't have the most athletic or orthodox swings but were really consistent and knew how to score.  Were they not better golfers than players with long, aesthetic but unreliable swings?   What do these players who learn just enough to hit playable shots know that most golfers don't?   Comments?  Is the game in your head or in your hands, and how does your approach to improving at this game (or the mythical optimal approach) reflect your answer?
    • FWIW he played his third double round in three weeks.  90 and 96.
    • It's a disappointing end (w/ or w/o "closure"), but I've got no hate for Dan. Yea, even w/ the same final outcome he could have handled things better to the people following him. But really it never cost me anything and I was entertained when he was still at it (regardless of any issues w/ his approach to the project and/or how he portrayed it). He also made it easy to follow his story... I remember checking out his stats page every few months, and it was kinda fun to just see it. I'd prob still give it a google if I heard he was trying for the Senior tour in the future.
    • I had 2 in my last round on thick and grainy poa annua greens.  Both were from over 30 ft.  One was uphill and against the grain.  I thought I hit it hard enough to get there but came up 10 ft short.  I was first to putt so didn't get a read on the grain.  The other was a left to right breaker and I didn't realize the grain was also running that way.  Ended up about 10 ft below the hole. 
    • I agree with @Buckeyebowman. I was practising my swing on the range yesterday and was putting some business card in front of the ball. Very pure ballstriking almost no mishits, straight ballflight I swept the card away every the time. I was focusing on my swing and the card. Then we got on the court. First hole perfect ball striking I was able to focus behind the ball and on my swing.  Then second hole I made a mistake with my driver (know the reason now). But anyway my confidence was getting smaller. 200m to the hole. So I got my hybrid out "I have to hit this ball 200m very hard now". I still tried to focus behind the ball and the shot was OK. But far from perfect. From now on from hole to hole ball striking got worse. At the end I even hit in the ground in front of the ball with my sand wedge which never has happened to me before. My head was going "You have to hit this ball now!" No loose swings as on the range before. And no thinking about the loose swing going to the target. The more frustrated I got the more I focussed on the ball. I was noticing in the end I was focussing in front of the ball and on my swing but when I made the actual downswing my eyes got back to the ball which leaded to terrible shots. I noticed the eyes really jumped.  What this means to me. I have to practise to change my focus now every time on the range and make this a priority. I also tried widening my focus which really helped. But its a different task to this on the actual court it seems.
