First time poster so dont kill me for asking these questions

I have a small collection of boas. And just started my collection of bp's.

So my questions are these.
1) Best size cage? I want to use boaphile 36x24x11.5 or 36x24x17.5
2) Do your bp like to climb or need to climb this question will help with #1
