John, I was wondering if the foam forces you to add more weight to counter the bouant nature of the foam. Do you think the fly would be lighter and sink faster if you used anothe material? Less weight = less slpash. I wonder if you could tie the fly all feather? Maybe stiffened up with...I don't know. Glue Gun?
Also, I noticed when testing my shrimp fly that it sank well in fresh(tap)water, but I needed to add weight for salt.
I love the legs and claws.
One cast can change your day...maybe your life.
