Ron, you need to add an "s" at the end of Nyerge. Gil's last name is spelled "Nyerges".
As a note, because it seems like you're very particular about your ties, is that when tying the original Nyerges Nymph, Gil ties in the hackle tip as a 'tail' before he palmers the hackle forward. Source of the info: Gil told me.
Gil keeps track of the different species of fish he's caught on Nyerges Nymph variants. He's caught many species of trout (of course), bass, carp, bonefish, and even dorado and tarpon! No joke, seen the pictures. Of course, the nymph size and materials are adjusted according to the species pursued.
