I'm looking at grip recommendations for competition. The more aggressive the better. I was considering the Burner grips, which are grips that have the texture of skateboard tape. I've come across a couple threads talking about the Shredder grips. Best I can tell, these are from Larry Davidson, but they are not listed on his web site. I am looking for something agressive, and a hard texture (no rubber grips). What can you recommend for a complete no slip grip? TIA.
