In my experience (mine only I'm not dictating anyone else's opinion) corns are alot can I say...edgy? (For lack of a better word anyway) were as BPs in all honesty barely even move that much...which is why I love them as I do there is no worry of escape and such...but both have merit surely this is just oppinion.Jack:2 corns2 ball pthons 1 emperor scorpion
