Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

Dorsal view of a Holocentropus (Polycentropodidae) Caddisfly Larva from the Yakima River in Washington

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Perfect Candidate for a Woven Fly

But which weave?
Both the "Crisscross" and the "Mossback" (according to pics in Leeson & Schollmeyer) look to me anyway as being good candidates, but before I climb that mountain, was wondering if anyone here has a strong recommendation.

This reminds me of the time I met this guy who was good at weaving flies, so I tried to butter him up to give me a few. I did that by bringing him to a private spot where I had access. I put him on fish. He caught fish. He never said thanks, and I never got a fly. Oh well, hope springs eternal.

From the anal gills and the markings, this appears to be Agnetina--probably capitata.
