I've been looking at Yamaha Stratoliners, etc, too. Love my c10 but have had it 21 years and it is about time to try something else.
The thing I like about Strato's is hydraulic valves and air cooled. I've got too many vehicles and toys and the less maintenance the better.
Haven't ruled out a c14 either but the valve adjust doesn't thrill me and neither does paying the dealer $500 or so every 15-25,000 miles or so.
