What brand/gauge do you use for your drop a/b/c tunings?

He's laughing at YOU.
You better click that bastard.

Ibanez RG370DX
Peavey Valveking 112 (w/ Bad Monkey and GE-7 EQ)
I use .13 Dean Markley strings. I wanted DR but my store didnt have them in stock... but they work very nicely for a and b but i havent tried them for c but they should work fine
