You might check what the master Johnny St. Cyr used.

I once played a rare Gibson trap-door six string banjo which sounded wonderful.
I haven't seen one since. I don't think they make 'em anymore.

The problem is that banjos need to have ring when playing with jazz bands.
The thump gets lost. Too much ring isn't good either.

There are certain banjos that sound better when you play a full chord across the
strings and then there are those that sound better played single-string.

You might determine which you have.
