I'm stuck and trying to improve my speed. Any tips are appreciated. Right now I can play 16th notes at ~140 BPM with a pick, ~100 BPM with two fingers, and ~85 BPM with three fingers. I practice with a metronome and mainly increase by 5 BPM. I don't like playing with a pick because I have less control over the strings, but I find myself needing to use it more often because my finger picking isn't up to speed.
