Anyone have experience with both of these and can offer an opinion if one is any better in quality, comfort and durability or do they just look different?

 

I had the ISO's on my Fatboy. Now I have the Avon's on my Street Glide. I'd say the ISO's were more comfortable. They're more cushiony. The Avons are harder and seem like they start to make my hand hurt after a while if I'm not wearing gloves. I got the Avons because they had the contrast cut spikes on the end and they were otherwise completely black (Blacked out SG). They look great...but like I said, my opinion the ISO's are more comfortable. YMMV

 

Went through two pairs of Kury ISO grips, both throttle sides snapped off in my hands. Kury made good and sent me a replacement the first time, when the second pair failed I went with Avons. Yeah the Avons are stiffer, but the quality is way above anything Kury makes.

All that glitters ain't always gold!

 

Had both the avon were harder than i cared for and were very sticky on throttle control. Bought iso grip .... No Comparison soft and firm. Good throttle control.

 

What do you mean "sticky on throttle control"?
