eh, i strike a pedal on my freewheel bike every couple of weeks... never very hard, though, and it's never thrown me off balance or caused a problem. just ride w/ power and control and pay attention to your position and the limits of your equipment and you'll be fine.
another good idea would be to do tight turns on a fairway or preferably a putting green until you catch a pedal and fall so you can find out exactly what those limits are.
