Hi there, I have a 21* 910h with a Proforce V2 89g X and need to change it, I hit it too low. I use a 66g S V2 in my 910d2 and a 76g S V2 in my 17* 910f and love them but not the one in my hybrid. Tonight at Golfsmith I tried a 89g V2 as well as the 90g 'Ahina and 80g Kai'Li (all in stiff) from their cart/inventory. The stiff V2 brought up my launch angle, increased spin, and increased the angle of descent...all of which where needed and the Ahina was about the same as the V2. The Kai'Li did even more to all of the numbers, getting me to the point that I am happy...however I have a tendency to hook that shaft. Is there a shaft I should look to that can achieve those higher numbers but be more stable than the Kai'Li without spending too much? If I were to order one and get you guys to tip it how much with it effect the numbers I am trying to achieve? BTW I am a sweeper with my woods/hybrids have a 108-112 SS and a medium-fast tempo but pretty smooth. Thanks !!
