If you do both fingerpicking and clawhammer then you may want to look at Wildwood banjos, made in California. I have a Minstrel model and it sounds good both ways. It has a Fibre-skin head and a tubaphone tone ring. The pot is a full 3/4" thick, like a bluegrass banjo. The thinner walled banjos like Chanterelles or Chuck Lee will never sound "bluegrassy", IMO. You can even get one with a pop on resonator.
Deering makes a John Hartford model with a wood tone ring and pop off resonator, but it is very pricy. And you should know that Greg and Janet Deering are Scientologists, and include their literature with your banjo.
