Have you done any comparative testing of the TS1/TS2 relative to other brand’s irons in the category (multi-piece hollow bodies)? I’m finding my spin numbers to be considerably lower and launch angles to be higher than with other clubs (P790, AP2, T200, i500, 0311P, etc) For example, with a 7-iron ball speed of 115, I’m getting spin that’s sub-5000 RPM, and launch at 19-degrees or higher. I’m just wondering how much of it is me and how much is the club.
When the TS-2 first came out I made a 6 iron in as near as specs to a P790. I then put them both through the ringer in the launch monitor and found the numbers to be extremely close with the only difference being that the TS-2 was spinning slightly more. Launch, height and distance were negligible. The P790 in the sim rolled out a little more. I then took them out on course and found the results to be repeated in the wild. I found the TS-2 to be stopping as it should. I found the P790 to roll out too much for me. The shafts were KBS Tour 105S. I built a set of the TS-2s that week.
