I've personally used SA's Mastery lines, Rio's and Cortland's premium lines and all work well with perhaps a slight edge to the Rios. The biggest thing would be to find a line that behaves well in the water/air temps that you are fishing. Then other than that match the type of fishing you will be doing. Bass Tapers are designed to carry bigger flies at closer ranges. Bonefish lines put a premium on casting small flies longer distance in tropical conditions. Pike lines are for shorter distances, huge flies and cooler temps.
