First of all, welcome to the site! This is the best place to get pretty much any and all answers pertaining to our bikes. If you do end up with an America or Speedmaster I just can't see you being disappointed. It is a very capable bike, but not stupid fast like a sport bike. It will cruise along all day at legal speeds yet when you want to a bit more adventure a twist of the throttle takes you there. Handling is GREAT! The seat is nice and low so no worries there.
As a 'however' you may find you have to do some tweaking to make it nice and comfortable for you. Many (including myself) have changed the seat, or added risers to the bars, or put on floorboards, etc to set the bike up to suit their own body. Other than that I agree with others here that the forward foot position takes a bit of getting used to but after that, it feels normal.
