The One-finger-per-fret B Technique?

ibdastevie gave the exact same technique that I was taught, although I never knew where it came from. It is VERY useful and puts a lot less strain on your hand. There are situations where you will have to use your pinky and ring finger separately, but you will usually be able to use them together. Over time your hand will become bigger and stronger so it will not feel as uncomfortable, but using the pinky and ring finger together should be something you always do unless you have to use them individually.
