When you’re using a knotless tapered leader, the last section before you tie on the fly is the tippet. Over time, as you change flies and tie new knots, that tippet section will get shorter and shorter, until your 9-foot leader is more like 7½ feet. So, you just put on a brand new knotless, tapered leader, right? Wrong.
In this great video, Tom Rosenbauer shows you how to identify the transition point between the tapered leader and the tippet section, and he demonstrates where to attach the new tippet. If you’re not familiar with the surgeon’s knot, check out this great animated video on the Orvis Fly Fishing Learning Center.
