Hi, Just wondering what everyone uses for czech nymph shellback. So far I've tied them with magic foil pearl strips and 1/8" scud back. Is there any other materials that are good to use? Tied some and tried them out and caught fish in the tough part of the Quittaphilla creek, the delayed harvest. Brown w/black head worked. Weird part is only pulled fish of of two sets of riffles. Tried a couple of other riffles and nothing. I know know what was up with that. Only thing I can figure is the area I caught the fish was a deep pool. The rest of the areas weren't as deep, maybe that was it??
