Fly tying question

[Zeno]

Over Christmas, my good old dad was checking out Northwest fly tying magazine and hashing out an article about some whacko fly-tying-nut-job that had a new steelhead pattern for leeches. Called it a MOAL. Mother-of-all-Leeches. My dad, correctly, immediately saw that this same fly would be good for salmon, with a few modifications. It uses two hooks and a bunch of rabbit stuff etc but the hooks are connected with 'spectra'. Since my dad lives in the dark ages and cares not a wit what the rest of this cesspool of a civilization is doing, he is a bit at a loss about this spectra thing. What is it? - A new type of monofilament, choking wire, death grip boron/graphite/other fiber, super dooper strong spider wire new –fangled-thing-a-ma-bob or what the hell is all this new stuff.

Any details or information will be appreciated. I’ll post a fishing story in ‘payment’.

Smart-ass retorts by non-fly fishers will be politely ignored.
