Hi,
In another post, the footprint of the fly on the water was mentioned. I believe that the Water-Walker style of fly produces a perfect footprint.
Perhaps I have not done justice to this pattern in this particular fly, but I can tell you that you could throw the fly to the ceiling 10 times and it will land perfectly on the floor each and every time. The "feet" of the fly come out at the sides as the insect's feet do.
