The Scientific Anglers AirCel Supreme 2 is a classic fly line that was popular in the 1980s and 1990s. If you have an old stock version of this line, here are some key details and considerations:

Features of the AirCel Supreme 2:
– Weight Forward (WF) Design – Optimized for smooth casting.
– Floating Line – Designed to stay on the water’s surface.
– Durable Coating – Scientific Anglers’ early formulations were known for good durability.
– Versatile Use – Suitable for trout, bass, and general freshwater fly fishing.

Considerations for Old Stock Lines:
1. Condition Check
– Inspect for cracking, stiffness, or discoloration—signs of aging plasticizers breaking down.
– If the line feels sticky or brittle, it may have degraded.

2. Performance
– Older lines may not perform as well as modern counterparts due to advances in fly line technology (e.g., slicker coatings, better floatation).
– If still supple, it could be usable for nostalgic or light fishing.

3. Collector’s Value
– Some anglers seek vintage fly lines for nostalgia or collection, but they typically don’t hold high monetary value.

4. Modern Alternatives
– If you want a similar weight-forward floating line, consider:
– Scientific Anglers Mastery MPX (modern upgrade)

Final Thoughts:
If your AirCel Supreme 2 is still pliable and in good shape, it could be fun to fish with for a retro experience. However, for optimal performance, a newer fly line will cast and float better. Let me know if you’d like recommendations based on your fishing style!
