Hookedintheear, welcome to FAOL. Sorry I acan't help on trout flies but panfish flies is another story. Top water flies are a blast with gills. Try soft foam poppers and such, you can find patterns in fly tying section, yellows, black, tan and green seem to work well. Wet flies/nymphs, the caddis stone fly types. Try wooly worms and woolybuggers both, gills and bass will really hit them hard. Good luck and enjoy yourself here, John.
