Had some fun up in Canadian lakes with these. In the above photo with 4 flies... we had some of those, and also some that had a hackle spiraled down under the floss body, then trimmed the hackle hairs off to about 1/16", so there was a stubble around the fly. That one outfished the "bare" wrap so much we quit using them that trip, and ran out of the hackle ones. We musta matched the hatch somehow, Fish can get picky. I've never had luck with chenille in a lake, only in rivers. I think the big presentation works best in faster running rivers, where the smaller, more delicate flies have worked better for me in the lakes or very slow water.
