If you guys read back on page one, he already stated he would wait to breed.

That being said, I think if he is willing to wait, but wants to have 2 snakes while going into university, a rack is a good idea. They are a heck of a lot easier to deal with than single tubs (the lids get irritating when you just want to check on them) and also IMO, leave less opportunity for error/escape. You don't have to worry about if you put enough clips on, did you remember to clip back after changing that water etc.

As far as space, you can't get much more space efficient than a rack. Hell, a 3x cb70 can double as a night stand in a pinch.
