With Cadaverize I'm playing in Bb, currently with 14-68 strings. Seriously fucking heavy strings, but works great. I'm going to downgrade though to 13-56s or something like that soon though to get more crunch from the strings. The big advantage of the mega-heavy strings is that the last much longer before they lose their tone.
Otherwise I'm pretty much just shredding 80s hard rock on my ESP Eclipse with 10-46 in E/Eb. I used to play 11s for the high strings and 36,46,56 on the top three but that got kind of annoying.
