This is the second time i've seen a really compelling reason to go for swinging doors over sliding. I forget who, one of the boa folks, mentioned that having half a door to cling to makes getting recalcitrant boas out of their cages even more difficult. I like the clean space-efficient look of sliders, but i think once i upgrade my enclosure i'm definitely going to be grabbing a swinger (did that come out wrong?)
