greg, I hate to disagree with you, but the strong beat with frailing is always made with the index finger. I don't know about Scruggs Style & I ain't saying it can't be done your way, but typically, with frailing (clawhammer style - what ever you want to call it)the strong "down" beats is as I said,done with the index (or Middle) finger. I do reinforce my index finger though, in that I support it with my thumb, as if I were holding a flat pick.
