I would like to find a replacement grip to replace the original factory grips on the handle. Since I am going to put another overgrip on it, I don't need the replacement grip to be tacky. and I don't need very good sweat absorption also. All I need is, it should provides good cushion to absorb vibration well and this should last long. Anyone has any recommendation? Thanks
pretty much any PU-grip, or a 1.5mm+ grip (though I don't think leather will abosrb much shock).. See if you can find one with "EVA" in it, it's supposed to be shock-absorbing...
A replacement grip on top of your existing grip will provide superb cushioning. The grip will also be very durable, depending on what you get. I use Ashaway CushyTec. The wear is only moderate after 6 months of use, and the grip is harder than comparable karakal grips, and doesn't become too soft too quickly.
