Czech Nymphing Techniques or High Sticking flies for sale. This uses heavy Czech Nymphs fished close in fast water. Czech Nymph Flies use heavily-leaded hooks. 'Matching the hatch' is not a priority, this is an active searching method and as such, technique is more important than the actual pattern.
Czech Nymph Flies are intended to be fished very deep, in fast water, weight & a slim profile are important. However the key is to use heavily-weighted flies, so beadhead nymphs, tungsten flies and caddis nymphs will do just as well. 'Matching the hatch' with czech nymphs is not a priority with this fishing!
