Neal, some can be pretty defensive but at that size its no biggie. Others never bite, just depends on the snake. Mine never bit me until he hit about 6 ft when he went through a pissy stage.
He came from big adults, and with his current size at this age he will likely put on another 3 ft or so in the coming years. He is extremely cage defensive and I would not dare getting him out while he is climbing around on the branches (tried that once - he anchored about half of his body to a branch and then began lunging at me with the other half, and at that size he can hit me in the face from at least 4 ft away), so I wait until he is in a hide. Once he is out he is like a big corn though.I handle him once or twice a week and that seems to be a good median between not enough and too much. Getting them used to you when they are young is the key.
