For the past couple of years, I've adopted the following approach for fingerpicking folk rock/alternative music...
E - pinky finger
B - ring finger
G - middle finger
D - index finger
A - thumb
E - thumb
At this point, I'm super comfortable with using my pinky finger on the E. I personally think that it is the most ergonomic approach since I don't have to move my ring finger to reach the E (although I have to cover two strings with my thumb). I've started reading that the pinky is rarely used in picking. What are the pros/cons to this approach and should I forgo using the pinky in fingerpicking?
