These are the simple working nymphs: easy-to-tie and very strong. The body is made out of dubbing brush on the thinnest wire. Instead of the tying thread I use 0.12 mm mono line. All of these flies are heavily weighted - their weight is from 0.5 to 1 gram. Hook sizes mostly # 6.
These flies are designed for using as a lower nymph when fishing with the modified “short nymph” method. With this method of fishing, you do not need a fly line (I use 0.4 mm mono line). In contrast to the “short nymph”, I release rather longer line - from 2 to 4 meters plus the tippet. This allows me to fish at different distances.
