Contact this fella. He lives there and is a very good fly tier.
If this won't work for you I will try something else.
He also makes a great fly spoon for reds. I believe that he has a sbs on doing the spoon. If you have trouble finding it I think I have it save somewhere.
Sounds like a great trip. Wished I was going. Good luck.
I know Kirk as well. Great guy & very knowledgeable tier! He ties a bendback style fly with a rattle in the belly, called the Rattle Rouser. Clousers are great, but that rattle really helps sometimes when the water clarity is down. Might also be something to consider.
