I'm in the market for a new float rod post Xmas and I'm surprised at the line ratings that are being quoted. It's common to see very wide ranging line ratings, such as 2-6lb or 3-10lb and rods being touted as all-rounders but can a rod be an all-rounder? Can a single rod be comfortably used to fish light stillwater blues for small roach and rudd, and then used the next day to fish avons in a fairly brisk current for chub and barbel?
