@wellingtonrock My hands are quite large as it is (when I was in practice I was an octave plus like two semitones on a keyboard). I've been focusing on a classical guitar for a few years now, which has a nice wide fretboard (like 52mm) and a 650mm scale length.
Which is actually one of my problems on my standard mandolin: it is very fast, but feels cramped to work with if I fall out of practice. So I'm okay with with the tradeoffs there (I've also been eyeing an octave mando, MAS is a thing).
