The Foamulator is the latest incarnation of the Stimulator, from Randall Kauffmann. Let me tell you, this fly has ALL the bells and whistles. The addition of a foam overbody, underwing, flash, rubber legs and indicator post make this fly a contender for the most dramatic makeover award! The foam adds a huge amount of floatation, as well as keeping the fly from soaking through over the course of the day. The rubber legs add some fish-attracting appeal, the flash a nice touch of color and movement. This is a great fly for dry/dropper rigs and can match stoneflies and caddis as well.
