The only thing I don't like about APs is the sliding doors. With Boaphiles, or any other version (that's all up to you), the whole front drops down and that is much easier to take a full size girl out than only using half the cage...her tail will hook around it and make it a project....guaranteed. lol. If you want to go with a 6 foot cage, that is most likely better if space is not an issue and neither is funds, then make sure you use a 1.5-2 foot tall one instead of a 1ft tall one. It looks better and makes it more "eye appealing".

If you like the T20s from AP, I'm going to recommend the swinging doors. This may just be preference, but I'm not a fan of the sliding doors at all. If you use aspen, it will get all crammed into the grooves and so on. They aren't my favorite design at all. They are a pain. lol.

As for visions, the thing you may want to consider is the option for lighting...if you are going to use this new cage for a display...this will be a nice feature.

Hope this helps.
