How important is the pinky for technique and speed? I ask because I broke the knucke of my frethand pinky, so it snaps when I bend it which makes it hard to use it while playing. Does this mean that someday I'll hit a level and never be able to improve because of the pinky, or is it possible to be an excellent guitarist without much pinky use? Also, it's fine for chords. It's only a factor when I'm playing lead roles.
