Interesting flies, but those weren't what I was expecting. A very common
fly in the Scandhoovian regions is a "Skating Caddis", something which as
of yet, seems rare in the shops I have looked into. The folks at LLBeans
had never even heard of it, yet it was the most productive fly at both
Lapland Claves I attended. I still use it as my 'secret weapon' when I
fish in New England because I'm quite sure the fish have never seen one
before.

Thanks Riverman I'm going to add the "Skating Caddis" to my arsenal.
