Not sure I would put so much weight on one "option." I use the Kaoko Throttle Lock, and couldn't be happier.
Considering I do mostly state and county highway riding, I probably don't need it either most of the time (cruise). I just need what you have. I have seen it on WingStuff, just gotta pull the trigger.
