I’ve used this thread for several months on both dry flies and nymphs. It holds well under tension and doesn’t fray easily. The 100-yard spool is convenient for small batches of tying. Consistent quality and reliable performance.

Great for tying delicate patterns. The flat profile allows for clean, precise knots. I appreciate the strength without being too stiff. Perfect for both beginners and experienced fly tyers.

Solid thread with good durability. A bit more expensive than some alternatives, but the strength and consistency justify the price. Works well in both wet and dry conditions.
