Ooo - all sounds very complicated, and I'm sure I will get there!
For the meantime, I'm just concentrating on C tuning and chords, and sussing some nice rolling finger pick styles - thumb and 3 preferably. Involving that 5th string I guess is the trick, and the run probably needs to be different to those my fingers already know (guitar). And then there are the 4/4 3/4 etc.
Most sites/books tend to focus on frailing, clawhammer or scruggs. Guess I'm wondering if there is another way?
