Regardless of the old fashioned design of the Dave's Wooly Worm history has proven time and again just how effective it truly is. Dave's Wooly Worm has demonstrated superb results with trout, bass and pan fish when the newer more sophisticated patterns simply weren't working. This fly can be used with dual purpose, it can be an imitator and it can also be an attractor which is an unbelievable achievement for a single fly. This variant of the Wooly Worm does give the hungry fish a profile view that looks definitely more buggier.
