Hm, I have 40 ball pythons, which get handled when their cages are cleaned, when they are being weighed and checked over once in a while, and when I'm moving them around for breeding.

Their temperaments are largely the result of their genes. We have not spent a considerable amount of time handling them. They remain non-aggressive. We had one aggressive female, but sold her some time back.

Our largest girl weighs 3500 grams. That's under 8 pounds. So I don't think you'll have any problems with handling ball pythons.

Corns move faster--they're much more active, alert, and fidgety than ball pythons.

Hatchlings of both species can be nippy and very nervous, but they generally grow out of it as they get older. I think corns are more prone to stay nervous if not handled frequently than balls are, but I haven't worked very much with corns, so you'd have to talk to someone that does to be sure.
