Over time, I've really begun to dislike drop tunings and super-low tunings. All my guitars are in D standard, which suits me just fine. It's got some natural heaviness from the slightly lower tuning, but enough string tension to retain note clarity. It's the same reason my action is on the high side as well. I prefer having to dig into my guitar if it means a cleaner overall sound. I don't have the patience to constantly be setting up my guitars, so I'd rather keep them fairly close to E standard tuning. I also play very power metal-influenced stuff, so it just works better. In any case, even with a standard tuning, you can fret barre chords just like you're in a drop tuning and get some beastly, growling chords. Theory buffs, feel free to correct me, but I believe this is just playing fourths. You can be in E standard and still sound like you're in drop A or something, just by barring with one finger. I use skinny top heavy bottom strings as well. I don't know the gauges off the top of my head, but they work really well with my tuning and playing style.
