Probably a worthless question, but does grip size have any effect on flipping through the impact area? Other words, if you are using a grip that is to thin, would that increase your chances of flipping?
I honestly don't think so. My grips I have on my TM 300s are actually TOO THIN and i mash it just fine. I was also hitting Tom B's clubs at orlando which are SUPER HUGE JUMBO grips and it wasn't a problem either.
