SVonhof just doesn't really wear and as a company selling grips, that's not a good way to do business!
He must not have been with GP very long, to say something like that. imo, the worst grips used to be the GP TV. Thin, tackless, and would literally rot/get slick/hard just sitting for a few weeks. Their newer GP TV grips now have taken the place of Lamkin CL for me. And, I have been a Lamkin CL user since Arnie was born. Well, at least a long time back.
I've used the GP TV 360 grips all year and they show no signs of wear. (no glove)
