Frequency Boost, built a half-size heavy, provides just that. This general purpose floating fly line loads quickly, turns over large dries, nymph rigs, and streamers with ease, and features a mid-length head perfect for nearly all freshwater applications.
I put the 6wt on an old mid-flex Orvis rod and I've been very happy with it. It is limp and doesn't coil up in cooler weather like some lines. It's a good line for a beginner or novice when you're working on your casting skills.
