  1. Specific Gravity of other textile fibers.

    Just a few comments on textile fibers that work for me.

    Polyester works great for dubbing. It binds well to itself or when mixed with natural fibers. 

    Aunt Lydia's rug yarn (Polyester) sparkles in the sunlight which I feel makes the fish want to take a closer look.

    Poly Yarn (Polypropylene) is good for dry fly wings, posts, and has a SG of .90 which makes it light weight and floats.

    As an added bonus neither of the two above materials will hold water.

    Trilobal Nylons also sparkle in the sunlight and are readily available.

    I finally figured out how to make the fly dive and wiggle.

    A wider lip with an angle from 22 to 45 degrees, and line tie placed further from the nose of the fly causes it to wiggle.

    Tapering the nose helps some but not as much as mentioned above.

    I chose an angle of 45 degrees as it seems to be optimum for wiggling, while still able to dive 3 to 10 inches depending on the speed of the retrieve.

    To make it more of a diving fly is just a matter of decreasing the lip angle closer to 0 degrees.

    Notes:

    1. Angle of the lip is defined with the eye of the hook oriented vertically where 0 degrees is parallel to the hook shank.

    2. Lip material changed to 2 thicknesses of a 2 liter soda bottle (PET) as this plastic is much stiffer than the milk bottle (HDPE).

     The stiffer plastic (PET) prevents the lip angle from changing over time when fishing.

    3. Hook: Mustad 9674 #1 5X Long
