My favorite bike has a lot of BB drop, 80 mm. I don't know if that has anything to do with why I like that bike so much, but it rides really nice. That said, I have to be careful when riding that bike to remember not to pedal when cornering. My pedals have struck the pavement more times than I can remember on that bike, and it's always a bit of jolt when it happens but it's never caused me to spill. Anyway, that's something to keep in mind if you tend to pedal through the corners.
