I don’t know the actual split and I’m not going to look it up but the 440cc driver is still VERY common on tour. Is my 440cc driver easier to hit than a persimmon? No doubt, but I’m not sure what that has to do with anything we’re talking about.
Tiger made it “cool” to play golf so we ended up with a generation of “athletes” playing golf, not just a bunch of golf only guys. These guys are bigger and stronger, it’s pretty damn obvious if you watch any modern tournament compared to a re-run. Since they are bigger and stronger, guess what, they are dominating courses to the point they’ve had to make them all longer and tighter.
ANYBODY can get stronger, I’ve seen it in our gym with my own eyes. That’s the point.
