To me the stippling of the DVC grip and the texture on the CK grip feels like it produces about the same amount of friction. Neither are overly aggressive, which is probably a good thing. But realistically who cares? If you need more friction just put some grip tape on it. Personally I prefer smooth grips so I can put grip tape where I need it and leave it off of where I don't.
Thanks, that's what I wanted to know. I like the amount I get now, looks like I will be giving CK a call.
