+1 on the Avons. I had some aftermarket HD grips and hated them. I chose the Avons in large part because of the cost, I'm not sorry. My next set will be Avons too.

 

I've had Kury ISO grips due to the overwhelming praise they seem to get everywhere. I think it is cause they are cheap and common. I will never buy another set after that first set. Gar-bage. And uncomfortable to boot. Currently have HD bran knurled metal grips, no cushion. Discontinued now, were on the bike when I bought it. I wear gloves with a gel palm and these grips are leaps and bounds better than the Kury. No experience with avon

 

I've had Iso's on several of our bikes and very much like them. They are comfortable and the chrome holds up well. I had a couple of sets of HD grips and the chrome wore off after about 3,000 miles.
