I thought that I'd like to give it a try also but I have reservations. Specifically safety related concerns. I would like to get away from spending $1000+ a year on rubber. I replace the tires at least twice a year as I commute 25K miles and ride the hell out of it on the weekends.
Financial benefits aside I think the reason I haven't done it nor do I plan on doing it, ever, are the low speed handling issues I have read about. It appears that the bike basically falls of off the edge of the tire very rapidly in a deep turn. This bike is designed to run in a groove of sorts and a CT changes the handling characteristics to that of a tank.
Good luck in your search.
