The Scientific Angler WF-450 Gr 100ft / 25ft Sink Head Optic Yellow Fly Line (NOS VTG) appears to be a vintage (VTG) or new old stock (NOS) fly fishing line from Scientific Anglers, a well-respected brand in fly fishing. Here’s what the details likely mean:
Key Features:
– WF-450 Gr – A weight-forward (WF) line with a 450-grain sink head, designed for fast-sinking performance.
– 100ft / 25ft Sink Head – The total length is 100 feet, with a 25-foot sinking head (likely a Type III or VI sink rate).
– Optic Yellow – High-visibility yellow color for tracking in various water conditions.
– NOS (New Old Stock) / VTG (Vintage) – Likely an older model or discontinued line, possibly from the 1980s–2000s.
Possible Use Cases:
– Deep-Water Fly Fishing – The heavy 450-grain sink head is ideal for streamer fishing, saltwater, or deep lake fishing where fast-sinking lines are needed.
– Spey or Switch Rods – May be suited for two-handed rods due to the heavy grain weight.
– Vintage Collectibility – Some anglers seek out older SA lines for nostalgia or specific performance characteristics.
Sink Rate Speculation:
Since it’s not explicitly stated, the 25ft sink head could be:
– Type III (~3.5–4.5 ips) – Moderate sink for medium-depth fishing.
– Type VI (~6–7 ips) – Fast sink for deep or fast currents.
Where to Find More Info:
– Check vintage Scientific Angler catalogs (1980s–2000s) for exact specs.
– Look for similar modern equivalents, like SA Sonar Sink 25 or Rio Depth Charge.
