I keep the bail open to my right (left hand retrieve), and keep my pinky on the bail to snap it shut, and let out line between my thumb and forefinger for control. Not a perfect system, and there is a slight delay, but it can extend a drift into water you can't reach otherwise.
And for float rods, the longer, the better, assuming it's not in tight quarters on the bank (and sometimes hiking in with a long rod can suck). But anything over 8' usually does the trick. I've bobber fished with a 7 footer, but the arm gets tired from holding the rod so high for too long.
