Ride all of them. Consider horsepower versus torque and which you prefer because there is a pretty decent swing amongst these bikes. If you're so inclined, shoot the VIN's to your insurance agent to make sure there are no red flags. Also, you don't mention if any of these bikes are modified or have been down.
I like all of these bikes but lean toward the Bandit. The big V-Strom is pretty top heavy, and the VFR is heavy and lacks power in the lower powerband.
