Why not go all out and make it drive 650yds, maybe we'd then see the first score of 18 for 18 holes.
If you took a real R11, a real R11S and a number of other drivers, hit each a number of times and averaged the distance for each, I would bet that none of them would be any longer than any other.
Up until last year I was still using a Callaway VFT driver which was a fair few years old and nowhere near the size of the current driver heads, and I was still outdriving the golfers I was outdriving before. In fact, I still have a Callaway Great Big Bertha which has an even smaller head and I'm sure I would get the same results with that.
I know it's all about income, but by bringing out all these new, longer and more precise clubs and balls, WGT are killing what was a fantastic game.
