That is about the only big issue i could think of without the wing when i was tying. Went to a small stream about fifteen minutes away from my house tonight and used both flies. I caught 6 trout. 5 brookies and one rainbow. All about 10-11 inches long. Four of them hit the winnged one( all brookies) and a brookie and a rainbow took the non winged one. All six fish were in about a 20 yard flat that has a constant depth of about 3 feet. I will be able to get out saturday morning before i have to drive and try these flys again. hopefully i will be able to stay late enough for the hoppers to get active.
