The reason I'm going with the smaller body guitar is that my Simon and Patrick dread gives me arm pains. I'm 5'6 in height, how does a grand auditorium feel compared to a dread?
I realize I'm a little late here, but I used to own an Ibanez dred. When I developed small tears in my rotator cuff, I couldn't comfortably hold it. Wound up selling it. Taylor's GA is more comfortable to hold and play without the pain I experienced when holding the Ibanez.
Your 412e-R sounds ideal for your situation! Glad you were able to find something!
