The small fly needs to be simpler. It needs to be tied carefully to swim and fish effectively despite its tiny size. With a good taper and soft hair even the small fly will look extremely lively. The micro-tube out fishes the hooked fly any time. Lighter and livelier with the chance to change the hook size and colour it's just the best design. We love our micros. Summer fishing, floating line a micro and there is not any better way to catch those fish. They are fished with a loose hook of your choice with just a small fixing tube.
