Sorry James. I've been out all day and just now have seen your thread.
I have to say I pretty much agree with everybody's take on your question here. From what you're saying will be your general riding parameters, I too feel either the America or the Speedmaster will suit your needs just fine.
The only reason I occasionally bring up my "complaint" about a never-was factory-built "Super Bonneville" or "Super America/Speedmaster", with maybe a 1000cc displacement and with about 20 to 25 more horsepower, and with better suspension units, is that I've always felt a little more passing power is never a bad thing, and that while I've always felt the boys at Triumph have done a great job with the frame geometry and weight distribution on these cruisers in particular, I felt the bikes were only "let down" with Triumph's decision to put the cheapest shocks(with little to none rebound damping, which causes "wallowing" in the twisties) they could seem to find to bolt on 'em. And thus, always leaving it up to the purchaser to go to the Aftermarket for a decent pair of shocks(and better fork springs up front too, btw), so these bikes can live up to their potential, handling-wise.
