Hello: Rather than install new grips, I installed a set of grip puppies $15, over my stock RSTD grips. The larger diameter is really nice. I too enjoy placing my right hand out on the factory end weight when the cruise is on. But found it a bit short, so I had a local machine shop custom make me a 1.5 inch spacer that now allows my entire hand to be off of the rotating grip when the cruise is on. It also gives me a little more pull back for comfort.
