Mormyshka, fine jigs
Fishing with fine jigs and spoons (Mormyshka) is what we consider the step in between ultra light spin fishing and fishing with flies. Using Mormyshka jigs is really universal, both regarding fish species and water types. It's no problem fishing a stream full of trout that we could not approach otherwise, or easily sit over water 15m deep and fish the entire column.
As as lure, it's no problem to fish the Mormyshka jig with natural bait (grub, worms etc.) or artificial bait.
