Mine's my first 'big' bike.. so I can relate to the question..
I was lucky enough to be able to take the current UK bike test actually on my america, too.. :-)
It's great. Handles well and gives a good 'secure' feeling, (way better than a mates very 'twitchy' sports bike I tried. Quicker than any cage away from the lights, but the power feels really manageable, it doesn't throw surprise power wheelies, is very responsive but very controllable. Love it. Just did a 185mile run today on mine, at an 85-90mph average, comfortable and feels great!
America / Speedy - you wouldnt be disappointed with either, see what you can get the best deal on, and yes, Black ones are of course fastest. (Black paint molecules are smaller, providing a smoother surface and reduced drag co-efficient)
