Thank you, Mark - you know I'm carrying a flatpick in my purse but I haven't used it for years since I'm a real fingerpicking fetishist, also when listening. So I can't do that picking with a flatpick, but I can with fingerpicks. Having tried it: I am using similar pickings myself, the main difference is that I do the last stroke with one of the high strings (i.e. mostly with my index finger rather than with my thumb) not with a bass string - that's new to me. But still (at least at the moment) it seems to me that it's not quite the same as Scruggs style. Maybe it's for the fact that I can only do strokes in one direction, but I'd rather suppose it's for that fifth banjo string. What's its purpose, how is it used?
