I originally bought the 910H 27 in 2012. The spec for lie angle at A1 was 59.5” and shaft length of 39”. Max lie angle at A2 was 61. For ages played a Kaili at 38.5” and A2.
Been playing the 816H1 27 since 2017. The only difference between it and the 910H was its stock length is 38.5” and the lie angle at A2 is 61.5*. I can play it at 38” and an 11g headweight. Optimal is 38.5” and a 5g weight. I’ve been using a 70g shaft since 2018.
I just now noticed that the TSR1 26 has a stock lie angle of 58* and length of 39”. Been playing a Tensei 70S (actiually soft stepped since it came from a 23H). An 11g weight barely attain a swingweight of D2 with the same 70g shaft I’m using on the 816H1 27.
Why is there a 1* flatter lie angle on the TSR1 26* vs the 816H1 25*?
