I've been drilling them lately on a Chartreuse Fly Rod Hula Popper with a Prince Nymph as a Dropper. Catching bass on the popper and sunfish, occasional bass and channel cats on the dropper. Also, had a lot of luck several weeks ago on on a local lake using a Chartreuse Woolly Grubber. One day I caught a mixed bag with that pattern including bass, drum, channel cats, and walleye - great fun!
