I found a half decent selection at Sportsman's yesterday (at least the one in Idaho Falls). I can't remember if they had those specific colors - I bought some clear and some olive - I like the micro size stuff for body materials.
The material I've been looking for lately is quill body. I hit two fly shops this week, as well as Sportsmans, and they are out. I may have to try Cabelas this weekend. I'm wanting it in olive, cream, and brown. Love it for dry fly bodies.
