I liked the addition of the furnace hackle to the case. Definite thumbs up on this. I use turkey tail for my cased caddis, but will add hackle from now on.
Interesting that you moved to a caddis emerger hook. One of my thoughts was that the cases (at least for the Brachycentrus I try to imitate) are straight, so why go curved?
Also, why the wing case? I don't think larvae have wing cases, do they?
