This is reprinted from a Fishing World article.
If your flies are thin, build up the profile, by tying the material on top of the previous.
I tie FPF on a tube for billfish. Easy to change tandom hook setup and close the gape of the hooks.
For smaller flies 4-6 inches I tie the ALF. My ALF is basically streamer hair tied on top of the hook. The hook is fully exposed and you get the full use to the gape.
Lay down some thread on the hook. Cut material twice as long as the fly. Tie the streamer hair in the middle about half way down the hook. Bend the material pointing toward the eye back. Tie it down. Use about a little less matchstick width of material.
Tie more material toward the eye. Build up the profile. Whip finish. Apply 1st coat of epoxy. Add eyes when epoxy still a bit sticky. Press the epoxy to flatten it and give a better profile. Apply several more coats of epoxy.
Throw at an angery fish.
