You have a real 'soulmate' in Chicago in terms of spey and casting but he is of all places in the pacific northwest right now! Go figure.
When he gets back I will have him contact you via PM. He is very knowledgeable on the materials situation, in fact he ties some beautiful spey flies himself.
I guess that doesn't help in the mean time.... what are you looking for? Most of our sponsor shops ship to order.
