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 small hooked fly any time. Lighter and livelier with the chance to change hook size and colour it’s just the best design. They are fished with a loose hook of your choice with just a small FITS tube fixing the hook.
