Because we learn from results, ballflight will almost always be your determining factor in regards to equipment. With that being said, get fit NOW to where you want to be so that the ball flight will respond positively to your changes.

I have showed this at every one of Lynn's schools and I think everyone got it. You can make a "perfect golf swing" and the ball fly off line because of poor equipment. Your brain will never let you make that swing again because of this poor shot. Eventually you go back to the swing you were making, your teacher has to spend more time with you and you both become frustrated.

I use clubs to change motion in my students swing because it is much easier to learn from ball flight than anything else.

I totally agree Jeff.
My point is that if someone is coming over the top and is trying to get in -to out -,unless they can make the new move ,they could end up with different specs.
