I mix styles too. Started playing banjo because I admired people like Earl Scruggs and still do but found the metronomic precision and virtuosity of bluegrass stultifying. I tend to begin pieces in 3-finger picking then use a kind of percussive frailing for intervals, switching between the two.

Some people find it offensive, I did some street playing at a folk festival last year and everyone smiled at the picking then jaws dropped when I put in the hammered chords although one person told me she thought it was cool and I thought she looked pretty cool so who cares? It's my banjo.
