D'Addarios mostly, sometimes GHS Nickel if I think it's going to help - "help" what I don't know.... I'm kind of psycho about string gauges, I play guitars with 24", 24.75" and 25.5" scales, and 7-strings, and 10-string pedal steel C6th - I have more loose strings than the local music store, for sure. I like the feel and tone of downtuned, heavy strings too (not grindcore metal riffage, not hardly). GHS makes a set called GB-LOW that's 11-53, designed with special cores to be tuned down a whole step. I always have at least one guitar with a wound 3rd G string on it, and another guitar tuned to C G D A E G, low to high - Robert Fripp's "New Standard Guitar Tuning" or "octo-mando" tuning or whatever you want to call it. I used to keep guitars around in different open tunings but I just got confused more than usual.
Here's a fun thread about tension:

He researched D'Addario's string tension guide to determine what would be needed to get strings of equal tension - these listings are for a seven-string, obviously. The main conclusion is that most packaged sets have a low E that's way too small (and a wimpy low B on 7-string sets).
And b0b's pedal steel string gauge chart (drop these down each a few thousandths to find open guitar tunings):
