Im not sure how much money your wanting to invest or what actual cruise control is out there but if your thinking of throttle locks (and the vista grip does look good but like Dann said, after market grips) this is what I have on my TC and it works great. I really like the brake dissengagement. http://www.cruisercustomizing.com/mo...l/part/BAW-MCC
I have the ISO grips with it (took a little tweaking) as well as the Throttle Boss (on both grips for uniformity and use) and think it makes a good system for the older bikes. It does take a little to get it adjusted correctly but once there it holds well. Have rode a few thousand miles with it and happy.
Keep us posted on what you go with.
Safe ridin, Tim
