Jesse; I've been known to be a bit "Testy" but not "Grumpy". A warm water fisherman would enjoy the Duck as you never know what you may hook up! I've caught Rainbow's, Shell Crackers, Rock Bass, Small Mouth's, Large Mouth's, Walleye and Gar! All on the same fly!! I'll even get WarrenP to come along, he can catch fish out of a fresh mud puddle (no lie)! Wooly Buggers, Hare's ears, Soft Hackles and PSC's.
