Simple changes like the local adaptations suggested by USGA for OB or lost balls. Raking footprints and dropping from knee height in a bunker if a ball comes to rest in one. Playing out of a divot.
I'm sure there are a handful more but I don't have any more on hand right now.
Those are all perfect examples. I completely agree with a rule change on these. But does it need bifurcation? Or just an over all rule change?
As said, bifurcation in the form of individual adaptations for a club event to a pga tour major already kind of exist, and I am completely ok with. I just dont want two rule books. I hope this makes some kinda sense.
