My Taiwan is not a biter, but he can be very fast and tends to get wrapped around things. Most snakes (even corns) tend to be aggressive at feeding time (hey, at least they're healthy, huh?), and by the time a beauty would get to the size when the bites would hurt at all, you'd probably figure out how to feed it safely. When I drop a mouse in my beauty's cage... he catches it :). IMO, they're really great snakes, and the only thing that makes them any harder to keep than a corn is their size.
