I just traded my America in on a beautiful Cranberry Red / Black Thunderbird and I have to tell you the "bird" is sensational. The America was terrific to ride but the Thunderbird seems easier and more responsive in terms of handling. Early days yet but I am very impressed!
Absolutely correct - been there, done it.
More poke, better balance, smoother ride.
Only complaint, after about 100 miles, sore arse. That's with the long haul seat.
