On my Universe UV7BK: D'Addario XL130 (.008 - .03
with a D'Addario or Dean Markley .048 for the low B.
On my RG7-620GN: D'Addario XL130+ (.0085 - .039) with a D'Addario or Dean Markley .048 for the low B.
(On my 6-strings I use D'Addario XL120 (.009 - .042).)
Light, I know, and a fair variance. But it's intended to make them all feel as close to completely equal in string tension as possible.
I manage to get a decent sound out of them, it seems - I have a light touch, I guess.
I currently have an MP3 available in the Multimedia: Upload Pictures and Sounds section. It was recorded using my RG7 straight into my POD 2.3, and straight into a recorder, in case someone wants to hear these oddball strings for themselves.
