Well, as one Tour Master, I'm just hoping that if and when I ever make Legend, there'll be longer equipment available to make up for SOME of the difference. I'm trying to bring my level up by 1 every other day, because I suspect that when (not if) longer new equipment comes in, it will be at level 100 or so.
The top 10 PGA players in driving distance average 300 yards or better, and the top 100 are about 290 or better:

Lots of interesting stats there. I would imagine that WGT 'virtual' stats would be in a similar range.
