I was hoping someone could enlighten me. I fished a great simple dry fly known as an EP dun that uses EP trigger point fibers for the wing and floats like a cork. I really want to tie a few of these patterns up to match my local bugs and I do have some regular old EP fiber in a dun colour. While searching online I have been unable to determine if these two materials are similar and interchangeable or completely different. Since there is no hackle on the pattern the floatation of the fly would be due to the yarn alone.
I hope someone can shed some light before I overpay in shipping and duty to get my hands on this material.
Really appreciate any and all responses.
