Pro's: 14 yard loss an a 300+ drive will turn the game from drive + half swing wedge into drive 3/4 swing wedge. About as exiting to watch as it is to play. To bring back the 'old' skills of iron play the rollback should be at least 50 yards.
Amateurs: losing 10 yards by having a higher spin ball can be easely be compensated by using lower lofted drivers. And having some extra spin on the iron shots to the green will be an advantage to them. The problem lies that they will loose 5% on every shot. A 500 yard par 5 will play like a 550 yards and most amateur courses just do not have the money to move all they tee boxes forward.
Changing forgiveness is even more absurd to do if you just compare the impact pattern on a pro driver and a 10 handicap driver, one does not need to be a rocket scientist to see who will be severly affected and who doesn't one bit.
The only thing that makes sence is making courses tougher for pro play.
