Dwight, I would strongly suggest that you pick up Mark Mandel and Les Johnson's book, Tube Flies: A Tying, Fishing and Historical Guide. The book covers a broad range of flies and tying techniques. I have been fortunate to take a tube fly tying class from Les Johnson that has resulted in me tying many of my patterns on tubes. It was exciting fishing for large Coho in the salt in Tofino when the Calamarko Pink Squid was the hot fly of the trip. Check the book out, your tying will benefit greatly.
Best regards, Steve
