Stronger and less bulky than most equivalently sized 3/0 threads, Danville's 210d Flymaster Plus is great for heavy-handed fly tying applications where maximum tension is required. An exceptionally popular choice for spun deer hair bass bugs, saltwater streamers, flats patterns and more, Danville's 210d Flymaster Plus exhibits a naturally level laying nature that makes for smooth wound tags and butts on salmon and steelhead, and beautiful bodies on smaller trout wet flies too. Conveniently pre-waxed and available in wide array of colors to please, give Danville's 210d Flymaster Plus a try. (210 denier, pre-waxed, 100 yards per spool)
