Here's what I'm using these days
1946 Martin D-18 with the David Grisman Bluegrass Experience and John Reischman and The Jaybirds. But I have been using my 1978 Martin HD-28 with the Jaybirds too because it has a Fishman Ellipse onboard.
I take out my 1996 Martin D-18GE now and then when the 46' needs a rest from the road.
With Dix Bruce I mostly play the 1978 Martin HD-28.
I use Red Bear Trading company's Tortis pick 1.65mm. I have a Jim Nunally signature model with them. I have been using these picks for over two years now and they work perfect, as good as any shell picks I have ever had.
