Maybe you would benefit from the classy lizard hammocks? Sounds like everyone else is really happy with them. also the drift wood is harder to clean in my opinion. I use the ceramic type climbing fixtures right now and they are really easy to disinfect and clean. You can get really large al the way down to samll stuff for 10 gallons. They are super easy to clean, just throw em in the dishwasher but they are a little more expensive than driftwood. I would recomend them over drift wood ANY day though. You can pick them up at PetsMart or Petco... you know. Not sure about online places maybe LLLreptile though they tend to be kinda pricey. There are several other places in the dealers list of Kingsnake under supplies. Hope this helps!
Would love to see a pic of how you rigged up the visions so you could stack them if you get a chance!
