A 25 yard pullback isn't likely to be the same as a 10% reduction in distance. If the USGA does it right, the pullback will mostly affect the driver and affect irons very little. If they attack it by controlling the spin rate off the driver and therefore the high trajectory/extra long carry that allows the driver to go so much further.
I may hit my driver a little further today despite not swinging nearly as aggressively as I used to swing it with a 21 year old back, but I hit say my 6 or 7 iron pretty much the same distance I did with a balata ball 15 years ago, and I think that's pretty much true for pros as well (modulo the stronger lofts and longer shafts they've got very few use true blades any longer)
So I really don't think there is much to save in ongoing costs for existing courses. It would help new construction by not needing as much land -- especially today if a course wants to be prepared for what might be in store 20-30 years from now if things keep getting further out of hand. If the USGA acted now, that'd allow developers to breathe a sigh of relief that the USGA intends to control things so they don't need to worry about leaving room to expand the course to 8300 yards for golfers in 2040. And of course it would save existing courses that want to "keep up" future costs in renovations to add new tees, move bunkers, etc.
I think there would be some golfers that would quit the game.
Craig Sweet,
If you think people will quit the game if the ball is pulled back, shouldn't we eliminate the ODS so that balls that allow Tiger to hit it 450 yards and average Joes to hit it 360 can be legal? After all, if you claim less distance hurts the game, more distance grows it (for those who think growing the game is a necessary and good thing)
Besides, if 0.5% of golfers have such a fragile ego they can't play a slightly shorter set of tees if the set they play today becomes too long for them with a shorter ball, is that really a big problem?
