I just bought .013 - .084 strings for my schecter c7, and tuned it from low E to B, I usually use .010 - .060 tuned from A to D, so this was the same thing except just each string was bumped over 1 and the .084 was added to make a low E, i.e. EADGCFA. I mainly did it because I was just curious what I could do with an extra low E, and what I found was that the tone was way too dark on it, just too thick, definitely great for bass but use as a guitar was too dark, no real punch to it. So yeah, and also I don't find that the thicker strings hurt my fingers the only thing I notice is, it takes a little more effort to move around and like someone said before shredding is basically out of the question. As far as tension goes, my schecter is 26.5" scale length, and so I use the string gauges I'd normally use to tune my 25.5"s to standard tuning (low E for 6 string, low B for 7 string), but I just tune down 1 full step, so therefore that's why I tuned to EADGCFA instead of F#BEADGB. And of course the only way to get a thinner gauge string to be able to tune to the low E I was using, and not be like rubber bands, would be to use a full length baritone guitar like 30" or even a bass, lol. Has anyone ever tried using a bass as a guitar? Like putting thin strings on it so it is like under 20 lbs. of tension. I'm gonna have to buy a bass and try that. After all I love trying things, that's probably more fun to me then even playing! well almost, lol. Oh and also the lowest I've tuned my guitar was with the strings I have now (13-84) and I tuned down to low low A, and I actually did the bassline of a downtuned song, it was like rubber but it sounded good it gave the slappy noise of a bass, it gave it presence, lol. Anyway I know I'm insane, so I'll stop talking now, later!
