I recently ordered some grips for my Ping G2 irons. They arrived, however the hole in the grip was only 12 mil, whereas the end of the clubs are 15 mil. I returned these, and then ordered some golf pride grips. Knowing the problem, I emailed the seller requesting advice. I was told to order the 0.6 grip. Again it is to small. The supplier also does a 6.2 size, but I don't know what this refers to. can anyone advise me ?
