STRaider - Like you, I'll relax, shake my hand out and such, but eventually toss it back on the grip lightly, so that I'm in the neutral riding position and can cover the brake, etc if I need to. My cruise is a Rostra universal electronic cruse that I installed a couple of years ago using info from this forum and the GL1800C forum to wire it correctly. Since the Wing uses a dual cable setup (i.e. one to open and one to close the throttle) I can feel the throttle tube rocking a little as cruise adjusts, but it's not bothersome.

On my R1200GSA, I put on the same model Rostra, but it's a single cable bike, and uses a separate cruise cam in the throttle cable "bowden box", so you don't feel the cruise doing it's thing.
