Description
GSP thread, an acronym for Gel Spun Polyethylene, is an extremely strong and fine fly-tying thread made from multiple ultra-thin fibers. It's prized for tying large flies with deer hair, streamers, and offshore patterns due to its high strength-to-diameter ratio. GSP threads are often slippery and don't have much feel, making them tricky to use but ideal for creating bulkier materials or when extreme strength is needed.
Key Characteristics
Exceptional Strength:
GSP thread is one of the strongest threads available, with a high load-bearing capacity that allows for very thin diameters.
Flat and Smooth:
The individual fibers are designed to lay flat on the hook shank, creating a very smooth, almost invisible, and secure hold on materials.
Low Stretch:
It has very little stretch and doesn't provide much feedback, so users must watch the materials to gauge tension
Sizes:
