Great job on the CBH and the LH. I am partial to the CBH. Go catch yourself a slammer!
Never tied a green one. Though I do see green ones in the fields. I fish the Lehigh mostly and no self respecting Hopper is anywhere near that river yet the fish seem to take the yellow ones. Are they taking it for a hopper or something else, who knows?
This style of fly is also adaptable. A few years back we had a great cicada hatch, I tied a few CB's with black foam, I added an orange floss ribbing, used clear crystal flash for the wing, and orange/black legs.
There were abunch of cicada recipes out there at time but this was the easiest/quickest tie with materials i had on hand (except the rubber legs)It worked well.
