The Owens Emerger is a good surface film pattern used as a trailer or with a small BB size tuft of yarn 6 inches above the fly. I use Enrico Puglisi “ Powerfull” tippet material for fishing dries and film emergers. I have recently been using Stroft GTM which my son Michael brought home from a trip to Paris, with excellent results. For fishing deep, my flurocarbon is always Seaguar.
