I had Avons and Ness Fusion. I have pretty big hands, but the Fusions were too small diameter, making them uncomfortable for me. The Avons were just right. I only got rid of the Avons because bike got knocked over and the grip got scratched up.
Check out grips by RSD (Roland Sands), thats all I will put on my bikes. Quality, comfort, and cool looking. I've had the tracker grips on my last 3 bikes and they are awesome. This last set the traction grips, I will have from now on. They have a cushion, tacky feel and are great.
i have these, close to stock for feel, not to bulky like ISO grips, but knurled rubber. never lose my grip with there. especially with me getting older i needed something i can hold, and my hands never cramp. http://www.ebay.com/itm/Arlen-Ness-B...FWGxK6&vxp=mtr
