There are times when conventional fly fishing techniques won't get your fly deep enough, especially in heavy water. This is the time to use a heavy jig-head streamer, combined with either a power taper floating line or a fast-sinking line like the depth charge. The object is to get your fly as quickly as possible into deep pools and runs where other fly-fishing methods just can't get your fly. Dave Jensen shows you how to do it--the method is not pretty but it is deadly on large brown and rainbow trout.
