When I play faster, up beat songs I wind up generating a lot of string noise because of the way I pluck. I tend to pluck downward at an angle. Only thing is I can't really figure out any other way to play these parts. At least, not one that's healthy. I've tried getting heavier strings to see if that might help since they don't move as much when you play them but it hasn't done much. Thinking of maybe trying flat wounds or pressure/ground wounds?
