I'm glad to hear that you have some experience. And I couldn't agree more about the tanks vs the tubs. Tanks can be harder to maintain temps and humitity but once you figure it out it's no big deal. And I just love to sit in the snake room at night and watch them all out and about.
A few weeks ago I got a really nice rack and filled it right up. But now I'm moving some of the larger females back into tanks. The folks here are pretty sharply divided on the issue but I do love my tanks.
