Hitting it 300 or close to it really comes down to technique. Obviously you have to have a swing around the 115 range to do it, but you will only get a swing that fast if you have the proper technique. It also comes down to natural talent. Some players are just not made to do it. I mean there are even players on the PGA tour who cannot do it consistantly and have come to terms with that, even with all of there professional teachers and such, they still cannot do it. I wouldn't put to much faith into it anyway. Seriously, if you can hit the ball around the 260 mark consistantly, getting thta extra 40 yards wont even help much, because most amatuer's short games are worse then their long game, so the closer you are to the green on your drives, essentially the worse off you will be according to stats.
