Recently completed my installation of a McCruise unit on my ST1300. During my road testing I was delighted to find keeping a LOOSE grip (basically just resting it on the throttle) didn't seem tto have much effect on keeping speed. Lots of hills on my test course so the CC was constantly adjusting. I'd be leery about keeping my hand too far from the brake in traffic, but out where there is lots of space between vehicles I could see resting it on the tank bag or my knee.
