I’ve been using this thread for big saltwater flies and bass bugs. It’s strong and easy to handle. The untwisting is smooth and the polyester material doesn’t damage my scissors. Great for tying large flies.

The 80-yard spool is long enough for multiple tying sessions. It holds up well under tension and doesn’t break during casting. I appreciate the consistent strength and color accuracy.

Works well for my bass bug patterns. A bit thicker than expected, but that’s what I needed for durability. The thread doesn’t fray and stays strong even after repeated use.
