right now i mainly play with fingers 1 and 2. but for some melodic parts and "tech" parts of my band's songs, I like to use 3 fingers, sometimes 4. but the thing is, I have no set order my fingers go in. I play it different each time. Is it better to have one consistant technique and get REALLY good at it. or is it better to be medicore at playing the same thing using different techniques. also, should I bother developing dexterity in my pinky on my picking hand? or is 3 fingers good enough?
