The "Briminator" and the "Cypert Minnow" were two of the first patterns I learned to tie. It was the bead chain that caught my attention first... It really makes for a bulging eyed "bug."
Plus, there's another advantage to the bead chain. If a light wire hook is used, like an Aberdeen, the weight of the bead chain makes the hook "flip" and the point rides up. They aren't snag-less this way, but it helps keep them out of trouble.
If a faster sink is wanted, appropriate size dumbell eyes can be tied on instead.
Another feature that can be applied is the One Feather Concept - where a single feather is used to make the entire fly.
I like a pheasant, "church window," body feather. Select one with plenty of the marabou-like under down - that fluffy stuff from the base of the feather.
Some if this fluff is used to make a tail, then the rest is dubbed on as both body and head. I do include a wire rib to protect the fluff body, since it's kinda fragile. Last, add the hackle section of the feather around the "neck," behind the eyes.
Not counting hook and thread, that's:
