I own 3 visions which are v400, v221, and v211. I also own a AP T10.
IMHO the vision cages look more professional, I love the looks of them and the one piece design and would buy all visions if it wasn't for the price. I bought the v211 and v221 used for real cheap and bought the v400 new for around 400 shipped. I could of bought 2 AP T8s for that price. I bought the T10 new in box from someone for a great price. I would of bought the T8 bc I don't need the extra 3 inches of height but I just happen to come across the T10. The T10 has swing doors which I'm not a fan of, I just don't like the way they look and really like the looks and operation of sliding doors. You can use rhps with any of these cages, I do.
Rhps are easy to install, only takes 2 screws. You shouldn't need a uth of flexwatt when using a rhp, the rhp will heat the whole cage. If you buy a 48 inch cage you would want around a 22-24x12 rhp and I set my thermostat to 90 and put it on hot side and get a 90 hot side 80-82 cool side. For any cage you would want a rhp that is about half the length x half the width. You can get rhps from reptile basics or pro products. If you explain what cage, species, room temp to pro products that will tell you exactly what rhp to buy. IMO a rhp is the best way to heat a cage.
Your snake should do good in a AP T8 or v400 with a 80w rhp from reptile basics depending on your room temp. Like I said above you can contact pro products and give some information and they will tell you what to buy, pro products is a little more expensive but make a really good rhp.
