Sorry I forgot to update...
Thanks to ryanextra for sending me the grab on grip covers (for free [up])!
I have only rode one time with them on, things have been busy lately, but I did about an 8 hour ride with them. They are really nice and comfortable, definitely better than just plain oem grips. They installed pretty easy over top of the oem grips, and add some diameter so it's easier on the hands(and are also softer). I will purchase them in the future when this set wears out, they do help.
