String Gauge for Drop D, C and B

[Jukle]

I enjoy playing all kinds of music on my guitar, mainly Metal. I use an ESP LTD Viper-50, and that is what I play the heavy stuff on. I use standard strings, and they seem to be fine for going to Drop D and C, but I want to get down to B as well. I don't know much about string gauges and what not, so what kind should I get?

Help please!

I'd say try some Beefy Slinkys or Not Even Slinkys.
