Sit on a variety of bikes, read reviews, etc. If you are worried about choosing "the perfect" bike (assuming you have a non-unlimited budget), definitely consider buying a used bike for your first bike. It will make it a lot less expensive trading up once you've tried a particular bike for a while and decide you want a change. I voted bandit as a first bike - it gets great reviews as an all-rounder for a first big bike, is cheap to buy a low mileage, late model, used one (cheap new too, especially this time of year), etc. I bought a bandit as my first big bike after short listing many of the same ones you have. Definitely have a think about how you'll use the bike most, like whether you need/want a fairing. Finally, ignore the boy-racers (everyone else does ) and choose what you want!
