Bob Quigley is best known for designing extremely effective Spring Creek flies for picky, educated fish. The Hackle Stacker is a great example and will prove its worth quickly if you choose to tie this fly on to match any of the classic mayfly emergences. Fish this fly to selective fish with long and fine leader/tippet whenever the fish are turning their noses up to standard offerings. And, watch for the “eat” that may be very subtle.
It is worth noting that the fly’s name honors the tying technique “stacking hackle” which Bob invented when designing this fly. He was truly a great innovator in the sport of fly-fishing and tying.
