A have a small nevus on one side of my ring finger tip. Not going to remove it because I heard of the people that died year(s) after removing it. I can play pretty much anything without it getting in contact with the strings. But I'm really concerned about A-shape barre chords (major chords with the root on a 5th string). When barring with my ring finger, and especially when moving it up or down on the fretboard it really gets in contact with the strings or frets. I tried to play them with "open A chord fingering" but it doesn't work very well as I go higher (smaller frets). Another option that have crossed my mind is to bar with my pinky finger but it doesn't have even 1/10 of the strength needed. Sure I can fret single notes with my pinky very well but not to bar.
I even tried to put my left hand "from the above" and "reverse bar" chord with my pinky and index finger. It sure does have some potential but looks so wierd :D
What would be your suggestions? Should I develop my pinky barring strength or try to practice "open A" fingering? Don't want to die at 22! :D
