Mark:
I would not do many things differently, because I am not designing for Tour players now. I am designing for the widest range of golfers, and simply sliding the scale back a little bit would not require a change of strategy.
That is not to say I don't think a rollback of the golf ball would be a welcome change; to me, it would be, because it would help to preserve some of the difficulty of the game for elite players, without requiring more acreage and further changes to courses. But I don't think it would affect the average golfer as much as most people think. If the rollback adds one or two shots of difficulty to the course, the average player won't miss it. But, I'm also in favor of bifurcation, and grandfathering in the current ball for 5-10 years, except in competitive play.
