Patrick, the guys that I play with that are that age can barely hit it 200-250 off the tee. They call ME the bomber and I don't hit it nearly as far as your mate.
What kind of 'roids is he taking?
Regardless of what equipment a player is using, he's not going to carry a ball 300 yards unless he he has a CHS of 100+mph and makes perfect contact with no sidespin. Most weekend warriors can't do that, (or only once in a blue moon) so it's a moot point.
The point was, even with advancements you won't see the average player even attempting to play from the tips on championship courses much less turning them into pitch and putts from back there. It's still a pro issue only.
The funny thing is, as a 15 index hacker, I get told NOT to play from the blacks because of some crazy rule courses implement to avoid slow play, yet if I play from the blues or whites, on most holes bunkers and such aren't even in play for me anymore, and it's too easy for me to hit through dog-legs, go figure.
