I use a variety of different guages, all of them elixers though...I am a true convert!
My prs is strung up with 9's
my Gibson with 10's
my Cort with 11's
and my baritone with baritone guage elixers...not sure what they are.

I really like elixers. I used to play Ghs and D'addario,both of which were pretty good, but I find elixers have nicer tone, and for longer (which the bloody should have, costing twice as much as any of the others)
