Limit the length of the gripNo. But then I wouldn't have banned the other long putters either. If it's that great then everyone would have been using them, but they weren't.
I don't think the "two points of contact" thing works - I leave an inch at the top of my grip which sits against my left wrist. So am I anchoring? Where's the cut off?
Make it that you're only allowed to touch the grip
That inch would then be illegal and you'd need to hold it differently or get a shorter grip.
To be honest, an inch of grip beyond your hands will make next to no difference to how stab,e your putting stroke is.
