Not for my bass, but for me! I just put a set of Daddario XL 220's on my p bass and the feel is remarkably different from the 165's I usually run. I feel very little resistance and lose my place way too easily. The only upside so far is these strings were made for slapping and popping and require very little effort. I going to keep with them and see if I improve with time. Did anyone else who made the switch to lighter strings have this problem?
