hey---glad to have you aboard. like most everyone has said, go with fit and comfort. I own an america, but just spent a phenomenal bunch of days riding a speedmaster.
I was concerned about the drag bar, but once i got used to them, about 10 miles or so, i really like being a bit forward and loved the difference the 16t sprocket gave in the snakey, snotty, sweet dream roads of north western georgia.
by all means RIDE BOTH. More than once. let comfort be your guide and your imagination will do the rest...
