Bela Fleck prefers a very tall bridge and radiused fretboard.  Here's a high-quality option should you wish to experiment with this setup.  Compensated. 1-3/4" string spacing.

NOTE:  This is not suitable for banjos with a standard flat fingerboard.

Bridges may have either ebony or Brankowood top. (Sorry, supplier does not differentiate between which top-wood each bridge is stocked with.)

*Brankowood is an engineered wood (produced through a process developed by scientist Branko Hermescee) constructed from sustainable pine (specifically Pinus radiata). This patented process produces a stable wood that is highly resistant to changes in humidity and temperature, with clear and warm tonal properties similar to that of ebony.
