I have a supervalked IS (interstate) with a Bigboy, and a trunked IS with a Lowboy.
I like both seats, but like the Bigboy better (esp for long rides and heat) (only 5'9").
But the beauty is the seats can be swapped back and forth to either bike with a single key turn.
My advice is to pick a seat your butt likes, and NOT a seat you think looks the best.
My butt hates all Corbins (after an hour), but my eyes like how they look.

A number of guys have put a bit lowered shield on their supervalks. If you might do this, you might want a bit lower seat to go with the lower shield. IE, don't decide on a seat ($), until you have already decided on risers, foot supports (peg lowering?), a shield, yada.
If you ride with that FL crowd, swap seats with different guys for an hour here and there and make an informed decision.
With luck, you might even trade the Corbin to someone.
