These flies aren't really anything to marvel at. They're just surf candies tied sparse and coated with two dips of Softex instead of two layers of epoxy. I tried to keep the profile slim, and the overall length is about 1.5" (size 4 hook).
FWIW, this color scheme (blue over pearl with silver krystal flash) was the pattern that absolutely hammered dozens of hickory shad a few weeks back in Rhode Island. They're very expendable (I can tie about a dozen in an hour) so I don't feel too bad when I lose a few.
