To my knowledge, Yes it was once quite popular. The impression that Scruggs' style was more powerful, etc, kinda pushed it off the map. But it has its place, and I would think you'd find some who appreciated it in SE Tenn. Anywhere close to Norris? Stringbean, one of my all time favorites, usually played with 2 fingers. Wade Mainer often did and does the same. So many bluegrassers are conformist, to the point of reactionary, about technique, so that bluegrass stages don't always offer the diversity of oldtime music. But there is plenty of tradition behind what you're doing.
