If you tie your own pike and muskie fly fishing leaders the Scientific Anglers Stainless Steel Wire Tippet is a nice product to build the leaders with. This knot-able stainless steel wire can easily be tied on to a monofilament butt section with an Albright knot. You can then either tie your fly right to the wire or use a snap to make changing flies easy. You can easily make leaders up to 7.5' in length by using Maxima #40 tippet in whatever length you want and tie on 18" to 24" of the Scientific Anglers Stainless Steel Wire Tippet to make a simple one knot leader. Use a simple 3 wrap fishermans knot (unimproved) to tie on the snap.
