What a silly argument.
If somebody can hit the ball straight all the time, the only advantage he has is, he gets on the green in regulation more than the rest of us.
Now, if he is getting eagles (or better) from the fairway, I would be concerned but that would have nothing to do with straight shooting, would it?
Does he one putt from anywhere on the green? Or does he hit every approach shot with 3 feet of the cup?
I have a tracball mouse that I can hook and slice with without ever touching the ball setup ingame. Am I a cheater because I spin my ball left or right as I swing my club?
Next we will all have to buy HB tee shirts so we can't be accused of wearing an opposing games tee shirts.
