I'm about to build some rat racks, and was wondering which route I should take? I'm sort of leaning towards the PVC pipe method that Tim Bailey uses, but it does seem that the tubing Reptile Basics recommends would be easier to install. It just seems that the tubing would be more prone to clogging and possible leaks with all of the elbows and T's that Rich recommends.

Any suggestions or comments regarding either or these two methods?
