I keep trying dreads, loving what I hear but just too uncomfortable with them. I play sitting. I had a GC3 and I think it was the smaller front bout or something but I had all kinds of back, wrist, hand, shoulder problems. I switched to a 000 and all of that went away which is weird because they're kind of the same but something is different. I think from trying, that I'd like a GA and have seriously considered last years model of the 714ce. I've tried smaller 00 sized guitars and really don't think I would last long sitting without a strap, just as uncomfortable as a dread but in a very different way. I'm tall for a woman, 5'11" and even though I love playing a short 24.9" neck because of the Light strings, I keep wondering if I'd like a neck that's a little longer. I think you just have to play something for awhile to see how it fits.
I've also owned different sizes and shapes, from dreads to OMs to GCs to GSs to jumbos, and I keep coming back to the GA, which is, in the immortal words of Goldilocks, "just right".
