Really it depends on whether you want to leave your bass in that tuning?
If you don't, and want to go back to standard tuning, then you just want the heaviest gauge you can find, probably 50-110, this will help with the string tension a little.
However, if you want to leave the bass in that tuning, then you have more options. For a few years I played and toured in C standard (C, F, Bb, Eb), I used custom wound Newtone strings which had a large core (the element that has a real effect on tension). If you enlarge the core, you can have thinner gauge (I had 45-105), tune down and have a tension akin to standard tuning.
Of course, beacause of this extra tension, you can't then tune the bass up to standard without fitting 'normal' strings. Different tensions will also probably mean the bass needs a setup for a luthier
Hope this helps

Great advice man, thanks! For now, I'll just go with 50 to 110 gauge! However, can't I just use a capo if I want to go back to standard tuning? Or... just move my fingers up two frets?
