You're right Ted...there's rolls AND rolls, and of course "rolls"! Speaking of those, Merle Travis has the weirdest way of playing of playing arpegiated rolls. Maybe Justa can explain it. He seems to repeat his thumb index rather than using (say) his last three fingers.

Chet's one of the few players that DID actually use his thumbpick for up and down strokes. Don't know why, but that just doesn't seem like a common technique.
