I do like the Jungle vines. I've got two of the large ones and one medium one wrapped in a complicated figure-eight thing, which I then wrapped with an additional piece of plastic foliage for a little privacy. I perch it on hides or hang it from pieces of cholla. It's a pretty popular climbing ladder.
My one complaint is that it sheds little bits of rubbery powder. So I keep it away from the water bowls, because I doubt it's made of anything the snakes should be drinking.
