Now that i am thinking about this, i figured i'd make an honorable mention.
Progrip Triple Density grips were some of the best grips i have used. i have used a LOT of grips on bikes over the years, and these are the only ones that have ever stood out in my memory as being awesome. i have renthal dual-compound half-waffles now, and i hate them. but my broke ass cant get the progrips right now (yeah yeah, 20 bucks, but i havent rode at all this whole summer......a couple times in spring, thats IT).
Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.
I've gotta agree. Been very impressed with pro grip for years now. If you have very large hands or do a lot of long rides give their rallye grip a try. Super super soft and large profile in your hand. You won't believe how long they last too and reduce vibrations big time too
