Yeah I think youre correct. Ive been looking around for the LARGE next. Or I may just go to the Win AVS Pistol. The white Iomic is just looking to get all dirty and ugly.
A quick way to get these grips "cleaned" is to use Coleman Fuel. Put some on a towel, wipe the grip and it'll take the grime and oils right out.
Also, works well with with regular grips.
I have Iomic's on all my putters. They are durable, yet soft and not "spongy". And unlike the Winn grips, they do not get "slimy" when wet.
