All Mahogany guitars can take quite a while to break in, due to the hard wood top. Bracing definitely plays a factor, as well. The Martin 15 models are generally well received, and the 000-15M / 000-15SM are models that I've seriously considered. I haven't played the Guild model mentioned here, but would be willing to give it a try, if I came across one.
I owned a couple of all-Mahogany dreads, and one of them was a tank. I kept it for six months, and it never budged, so I sold it. The other was a screaming deal I found on Amazon, where they temporarily posted at an extremely low price (maybe cost?). That was a decent guitar, but I never bonded with it and sold it (knowing that I'd easily cover my costs).
