The GP Tour Classic has been a great grip for me on my SeeMore's, a little bigger than standard but not too much.I thought the OS FeelTec was the putter grip of my future, but having used the Midsize Iomic, and then the standard sized FeelTec, I don't think I need oversize.
Tough call. I really need to start using air for my putter grips so I can switch them out easier.
