Well I'm looking to tuned down a whole step, not a half. I might have worded it weirdly before...what i want is essentially to tuned down a whole step, and ALSO be going to a higher gauge...So i wanna go lower, and add more tension...So is going to 12's and tuning a whole step down going to be about equivalent to the feel of 11's? Sorry im proabbaly still confusing lol

The key is that I want the guitar to sound and feel up to it's potential.
