The 333 Pro Series fly lines are species-specific tapers, engineered to generate high line speeds when used with modern action fly rods.
They are over-weighted to load your rod more quickly, have a longer belly to carry more line in air, have a stiffer finish to shoot through your guides more easily, and beefed-up back tapers to shoot further.
High floating and durable
