Re: fretboars raidius
Acoustics usually lie at the flatter end of the radius spectrum. On average, they run somewhere between 12" and 16" with Martins and Taylors being more toward the flatter end of that with Fender and Gibson being toward the more rounded end.
Note to pedantic posters: We know there are exceptions to every rule, and that is why we used the words "on average".
