I am trying to figure out what axiv shaft is right for me and i am very confused with the chart on line. assume a swing speed of 46 ms(=103mph), and i want a mid trajectory.
if i click the top tempo button i get a shaft 6564M.
if i click the midle button i get a 6568M.
If i click the bottom tempo button i get a 6572M.
the specs on each of these are
6564M=3.5 torque, and 268 cpm.
6568M=3.5 torque, and 279cpm
6572M=3.5 torque, and 291cpm.
Intuitively I would equate the 268 with a SLOWER tempo and the 291 cpm with an FAST tempo.
So i would think the top box is for slow, middle is for medium, and bottom box is for fast.
