The Alaskan S.T.S. Leech (aka the Alaskan Super Tungsten String Leech or the Alaskan Salmon, Trout, Steelhead Leech) is a deadly and improved version of the old S&B’s Super String Leech. The Midnight Crusher S.T.S. features a tungsten eye that gives nice jigging movement when stripped and a dubbed wooly chartreuse head and butt that add a hint of color that drives fish wild. If you like to swing for trout in Alaska, this is a must-have in your box for just about any time of the season. Whether you are fishing big rainbows in Bristol Bay or the Kenai or swinging for steelhead in Alaska or B.C., this fly will produce. Learn how to tie the Alaskan S.T.S. Leech in our tying video, get all materials needed to tie it on your own, or simply buy the fly.
