11-70 gauge strings

Im playing 6 string mostly in B, Ab, or C standard w/ low G#.
Obviously standard tuning will just screw the neck up but I just wanted to know the limit cos theyre real hefty strings.
I'm guessing drop C?
 
That depends on your guitar and your own tension preferences. A .070" would probably get me almost into 8-string territory. Why are you limited to this set?
 
Zakk Wylde signatures, I presume?

Watch your nut width and tuning key eyelet gauge. Those fuckers are pythons.

I actually put 10-60s in E flat for "training". Best rhythm exercise in the world.

But seriously, just stick with anything below drop B
 
I used to use 13-70 (wound 3rd) in C#. I was on a big strings = big tone kick at the time. It worked fine, but bending was a chore.
