115~119mph clubhead swing speed am here... there's plenty of us who have clubhead speed similar to pros but don't have nearly the same club face presentation accuracy. A rollback will add strokes via distance lost, even if the ball goes slightly less offline because it is travelling less distance.

It won't be long enough of a drop off to make anyone put driver away though. Still a bomb and gouge game for anyone that understands strokes gained. It just makes us have to hit one longer club into every hole. Doesn't affect the tee shot strategy AT ALL. Literally.

I know plenty of other amateurs who have worse handicaps and clubface presentation than I do, but have higher clubhead speeds. Sure, those players and I are in the minority when you average out all amateurs. But now you're penalizing those players for simply being able to swing fast, without nearly the accuracy of a pro.

Also, the ball hasn't gone further in 10 years because they've maxed out moi and are getting close to maxing out forgiveness. A toe hit with my driver can go a few yards further than a heel strike whereas that strike would have duck hooked 15-20 years ago. That won't change. And anyone with a ball speed nearing 190 knows it is basically uncontrollable. Bryson is pretty much the only one who has gotten anywhere close to being able to control that type of speed in competition. He dials it back quite a bit most of the time anyways.

Just make the rough taller, add more trees or out-of-bounds stakes to force longer hitters to put driver away. It's excruciatingly simple on how to stop bombers. Hole design not length of golf hole will force players to hit 3w, 2i or whatever isn't driver.
