When I'm playing on one string or moving from a low (piched) string to a high one I alternate 'twixt my middle and index finger on my right hand. However, when I move from a high string to a lower one (eg G to D) I tend to use the the same finger to 'rake' the two strings, which breaks the alternating pattern. I think this might slow me down; should I always alternate fingers, even when traveling down a string?
