@Adam C is a very knowledgeable club builder. Maybe he can help.

Bought a set of AGX one length iron heads only as I wanted to try the short irons 8, 9, w, s/w as same length shaft, I’m planning on making them 8 iron length and wonder if extending a 9 iron shaft a half inch would be better than cutting the 7 or 6 iron shaft . Can anyone tell me if they tried this before buying the correct shaft and what should work best for my trial???

 

cheers

That small difference probably won't matter for what you are doing here. In theory the 9 iron shaft will launch a little lower then the 6 or 7 shaft. Only definitive difference is the 9 shaft will play heavier assuming these were constant weight shafts and not blanks.

Can I ask if you know why there’s a 9deg diff between the wedge and the s-wedge, looks like these heads are going back because I don’t know how to make up the 9deg difference? I assumed that that difference wouldn’t be in a set of same length irons where the heads have the exact same weight, how does Bryson D cope with that problem is what I asked the supplier. Is it unreasonable for me to expect that I would not have this problem now, I have a gap wedge buy it’s different weight and length. ???

I wasn't ready to commit to same length, but I liked the concept of minimizing the differences in length. I built a set of irons with 1/4" differences rather than 1/2" differences built off 8i as my preferred length. I went same length (36) for both PW (43) and AW(38). Built these on Apex 19s and steel Elevate ETS 85 stiff shafts. Lofts and Lies are standard, except the 4i is 1 degree stronger and 5i is 0.5 degree strong. I needed to Frankenstein weight in the hosel on the 4i and 5i to maintain D2 swing weight. Please don't start the argument that they will overdraw, etc. They fly the same as the rest of the clubs. I am not the longest hitter (155 7i) and for me, smash factor is a big component of distance. I hit the center of the face far more often. Still working to generate more carry and more stopping power on the longer irons vs current shorter carry with too much roll. So far I love them.

The lengths go from 36 to 37.5 vs the standard for this set of 35.5 to 38.5. Reduced some variability and my swing feels much more repeatable through the entire set. I did not cut down my 3h or 3w. Yet.

Time will tell, each week dialing them in more and more. Handicap is dropping slowly.

    • 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?
