I almost exclusively use SpiderWire braid for all my fishing reels. They started out in California, but not as a fishing line. A company called Safariland was making high-end law enforcement equipment with high tech synthetics constructing bulletproof vests.
My favorite knot is the improved clinch knot. I’ve been tying it for ages, I can barely remember that I used to tie the clinch knot and saw on TV the improved version. It was probably Bill Dance, Roland Martin or Orlando Wilson that I was watching.
