I used a #2 sofa pillow with a prince nymph dropper. I had seen some stoneflies emerging recently and thought a big stonefly dry might work and also could act to attract attention to my nymph.
I dead drifted the dry/nymph dropper rig on a fairly tight line (we always called it high sticking, but with the rig we use and how we drag the nymph through runs on a very short line, now most people refer to it as the Czech technique) then skated the sofa pillow back up stream a bit. Most of my hits were on the nymph, but I caught two 20+" fish waking the big sofa pillow. It was like steelhead fishing a waking bomber! Maybe they thought it was a mouse... maybe a fluttering stonefly? Who cares! It worked.
I love big browns... I think I have an addiction problem.
