I still don't understand why none of you cannot comprehend that how a shaft bends and un-bends throughout the swing has a giant effect on launch conditions.
Where you tee the ball, what shaft you are using, how stiff that shaft is, what hinging you use, how flat/arched/bent your wrist is, how much axis tilt you have, how much leakage through impact you have, where you're hitting it on the face, i could go on forever.
This all has a huge effect on fittings on this is why i can do it better than most because i understand how it all effects given launch conditions. Most fitters simply look at the numbers and do what the puter says to make you hit it farther. Sure maybe that gets you "on the right track" but i'm gonna be the one who can help fix your leakage, then fit you into the right gear, and then teach you properly how to swing the driver to get the most out of it.
Go ahead ask questions. Do you use the turned shoulder plane? What hinging do you use through impact? What kind of loading action do you use? What's your tempo like? Again, i could go on forever.
Some hit up and some hit down, however when most people think they are hitting up they are still really hitting down. It just "feels" up because your HEAD is so far BEHIND the ball and you have a TREMENDOUS AMOUNT OF TILT. So if you are basically teeing up the ball at low point you are basically on the verge of hitting up and you "feel that." However i can position you in a way in your setup and ball position to really "hit up" and most people i do start hitting low snap hooks, hmmm......i wonder why?
They then do 3 things normally to hit the ball "decent."
1) The good players just angle hinge it and hit these monstrous "power fades"
2) Bad players will try start flipping at it or leaving the face wide open and they keep pulling or slicing the hell out of it
3) Some people start bending their plane line so far right they hit some REALLY BIG push draws.
