EG....I split around 15 quality fish last Sunday between this pattern http://www.riverflybox.co.uk/biot%20nymph.html as a dropper and Loren's Dark Frontliner on anchor. I was fishing a small local tailwater with a pretty nice Hendrickson hatch going on. Even got my first dryfly action of the year with a sparkle dun.
Good luck!...Jason
