I am currently playing this shaft in a Nike "tour" 460 8.5. I too was curious and looked into it. This shaft is 78gr. 3.1 torque and mid-high/high kick point. I really like the shaft, one of my favorite Fuji's! But with the BIG head, it is a little torque-y. I swing 119mph and quick tempo/hands. The shaft has a great balance and very good, lively feel. I tipped mine 1" and play it at 44.5". Good ball flight with no balooning!
Hope this helps!
