I wanted to share a video from a local legend, Brad Bohen. Brad is conducting a seminar at Bob Mitchell's Fly Shop in mid-January - I am stoked.
Brad's flies look very complicated, but after you watch the videos a few times you realize things aren't that bad. My first few were not great, but like anything else I'll get it it time.
Brad uses the Gamakatsu B10S hook in 2/0. I found the hooks on Amazon here for a great price. They are labeled as "Gamakatsu Black Stinger Fly Hook, 100 Pack", but when I got my order the box was labeled B10S. Great hooks! Brad is a fantastic fly tyer.
Here is a link to Brad's website.
