I have the ISO grips as well and I love the small throttle-rocker on the end on the right side, I just about never use the cruise control because of it. My wrist just doesn't get tired. But I'm sure the left side grip is straight with out a throttle-rocker on the left side........When enough snow melts that I can get out to the man cave, I'll have to look? Interesting!?
I like those heel rest a lot as well! Very nice!
