Fly tying wool that has been developed for specific purposes. Below is a description of each color.Chadwick 477 Substitute: This '477' has been developed by Semperfli to replicate as close as possible to the classic Sawyer Bug tying wool as originally used by Frank Sawyer. It comes as a 3 ply making tying of the nice thick Sawyer Killer Bug a doddle. However to perfectly replicate the original Killer Bug simply split the 477 Substitute from 3 ply to one and it matches even the diameter of the original 477.Oliver Edwards Rhyacophila: We used this many years ago and had great success with the original wool from Oliver Edwards. It had been discontinued but we kept some by for that odd very special trip. The team at Semperfli decided to get more to match exactly the original material from Oliver and we do not beleive you will get any closer match to the original Rhyacophila wool.Peeping Caddis Body: Peeping Caddis wool is just that, a wool which creates caddis bodies. It will can make lots of caddis bodies. Burn the end and it looks just like a caddis used for Hans Van Klinken Peeping Caddis Pattern.Perfect Shrimp: Perfect Shrimp wool is just that, a stunning pink shrimp body with that cracking pink loved by grayling. Simply wrap around the hook and add a shellback or wrap the wool as the body, Add Semperfli pink straggle string for legs then add a shell back for that stunning effect.
