This stuff is very similar to Straggle String but only with longer length fibers to act as legs that are FAR MORE DURABLE than natural fibers... Makes great collars, bodies and thorax's on a lot of patterns with a color pallet to satisfy even the pickiest of fly tyers. This material can be doubled for more bulk on larger fly patterns or coupled with Straggle String and furled together to make (extended or standard) bodies on many fly patterns. A cool tip is to alternate 2 or more colors twisted together or furled for material depth to use under wing cases on nymphs or extended bodies and it can be blended with natural fur like rabbit to subdue color tones. This product makes really nice "Krystal Buggers" (with or without hackle feathers) and other stillwater fly patterns as well. Another tip is to tie in and pull over a stretchy shell back material (like Semperfli's Scud Back) over a wrapped underbody of Straggle legs for a simple and ultra durable caddis larvae or stillwater shrimp/scud... Fabulous product, many uses, highly recommend!!
