Maybe they could red line fairways in tour events? max hitting distance is 320 yards, if over that bring it back. Seems an easy fix with no loopholes or messing with courses
I'm not sure what you mean? Make everything outside the fairway a penalty area?
Sorry if I was unclear. Put a limit on drive distance. Red line across fairway and rough, you cant hit further, if you do, no penalty just that the ball is brought back to the red lone, a type of drop zone if you like. Long drives will thus end, no course remodeling required
