After thinking about this, I think the best advice I can give is to go listening to other banjo players' banjos and go shopping around. I know a number of "cross-over" banjo players who come from bluegrass backgrounds and have been smitten by old-time...and I've been curiously observing their "taste" in selecting open-back banjos, and it's been all over the map. BUT...none of them are Mudcatters...
I could name names, but they might not be local to you...where are you located?
