I have both ISO and Avon Velvet Air. ISO seem a bit larger but I prefer the feel of the Avons. ISO has chunkier pads. Cant go wrong with either. A throttle boss is worth the extra $10 imo. L/XL hands also.

 

Got the basic rubber heated grips on my Tri Glide when I bought it. OK but not optimal. So I got some 1" wide Velcro with the hooks on one side and fuzzy stuff on the other, and cut 8 strips about an inch and a half longer than the diameter of the grips. I wrap them around with the ends where my fingers aren't.

Works pretty good, they don't slip, and I can use any combination of them along the length of each grip. They add about 1/8" or so to the diameter. On long trips I change them around each stop. Two on the just inside of each grip, 3 or all 4 on each, take them all off, etc.

If nothing else, it's a cheap way to see if a larger diameter is for you or not.

 

Here is an inexpensive option ($15) to add a little circumference to your grips while taking out a little vibrations at the same time. They will slide right over your stock grips, and for me, last about 10,000 miles before I replace them.

I use mine over the heated grips on an FLHTK, and actually think they spread the heat out even more evenly.

 

Ok, here is a little closure for this thread. I asked Santa for black magnum get a grips. I have installed them. Now I just need winter to go away.... thanks for all the input everyone.

 

I went with the ISO on my 14 SG with the throttle boss. I had a set of the fat ISO's on my 03 Fatboy that were perfect. However, the new ISO's do not come as fat and my hands do cramp up. I need to change out my grips. Thinking about heated grips?

 

Agreed! I have large (and old) hands and love the Magnum Get-A-Grips. I've put about 45,000 miles on mine. If I replace them, I'll get the same thing again.

 

I wasn't sure if the get a grips were gonna be for me, but with so many happy users I figure I might as well give them a chance.

 

Too bad the Get-a-grips aren't offered in a heated pre-TBW grip
