Finally got to see what all the hype is about. Special thanks to GolfWRX, TPT Golf Shafts, and Jacques Intriere at Greenwich Golf Fitting Studio in Greenwich CT.
A little bit about me, Tall, lanky, speed to burn. Played hockey all my life thru college, didn't pick up golf until high school and have been playing pretty seriously for the past 6 years or so.
I've been playing a M3 440 9* with a Kiyoshi Black 75 05 at 44 1/4", prior to that was a 2016 M2 head with the same shaft, and my prior driver to that was a Cobra F6+ with a Matrix 8M2 in X flex. Always fought launching high and spinning high, but have hit some of the best drives of my life with the Kiyoshi Black, it's comfortable, the weight fits me well, it's familiar.
Warmed up with some 7 irons, hit a few with my gamer and then we went on to the TPT Shafts.
I tried the 15 LKP LT LW and the 15 MKP MT SW. Since I normally play my drivers short, and these fitting shafts were a little longer I was able to pick up some club head speed, but I've always felt I've gained speed after a hitting about 30 balls and then generally tire out after 60.
I honestly didn't notice too much of a difference between the two shafts. I've been recovering from a torn glute and am pretty much back at full strength, so we did throw out some bad balls, but overall both shafts felt and performed pretty similar for me. The one thing that I couldn't believe is how STABLE these feel. Even from the "waggle" test the 1st time it just feels I didn't hit too many cuts with it, and while my bad swings still had some bad results, overall it just wanted to go straight. While I turn over my Oban at times a little too much, the TPT seemed to want to go straight. Ball speeds across all heads were low even on shots I felt I flushed. This could be due to the balls, the fitter had chrome soft x's and they appeared to have been hit a decent amount of times, I even broke one of them during the fitting, so that's possible but all other numbers seemed decent, so not exactly sure what happened there. **I will add, towards the 2nd half of the fitting my fitter did break out some new chrome soft X balls which I just remembered because he had to put the stickers on them for the flightscope, so not sure exact cause of the low ball speed other than the chop swinging**
It still launches a little higher and spins a little higher than what is desirable. My fitter and I both wonder if the 14.5 might help bring the launch and spin down a touch, which would help optimize my numbers, but since I was the 1st person he's fit into TPT and didn't have a 14.5 shaft we made use of what was available.
I still need to get the shaft and get it built and play a few rounds with it, let me know if anyone has any questions. And for those of you who have been worrying about breakage, was constantly swinging the TPT's 120 and over and didn't have any issues, so it seems that the problems that were had during the initial production runs has been corrected.
