I use Beartooth's Shocker Butts for steelhead fishing. Got lazy once and used that steelhead leader with the Shocker Butt for spring creek trout fishing. That was three years ago. I rarely fish without one now. They work wonders with light tippets. You will rarely lose a fish. One of the best adjustments I have ever made. The Butts have looped braided ends. I just trim one loop off and fix it onto my fly line if it doesn't have a loop.
