When I had my Vee I used a cramp buster and a throttle lock. It was effective but not as safe as I liked. But, it allowed right wrist and shoulder rest.
As for cruise, it came standard on my second S10. I still use the same cramp buster. I will not be without CC again on any bike for any use. I used to not feel this way. I also avoid long, boring roads. But, I find myself setting the CC at low speeds, like 35 mph even, to give my wrist and especially shoulder muscles a break. I love it now. And for that interstate that we all need to ride every now and then CC makes it as nice as possible, still boring, but nice.
But, like I opened with, a throttle lock is better than nothing and 90% effective as a cruise control.
