Very nicely done! I have tied them with grouse, and they are very similar. With the grouse, you get can get some dark spotting on the body, though that might be the only difference. I am not sure if that difference is significant. I would guess, depending on the stream
I do wonder, however, if on a cased caddis fly, do you want full length soft hackle, or if the hackle should be trimmed a bit shorter?
Again, nicely done.
