I like the in-depth descriptions of why you do things the way you do.

Excellent nod to Hewitt and a fantastic example!

Weird, I've never seen this fly patterns till today and I tied a dozens of these. Great job as always.

This is the best fly video I have seen, and I have seen hundreds. Your videos are really well photographed and clearly explained. However, what really made this stand out was the explanation of working with hackle. As advanced beginner/intermediate tyer, being able to get closeups of the hackles and hearing the explanations about the choices and how they're tied was really educational and enjoyable. I might suggest a separate video just devoted to those really close shots of various feathers and how they are used. Excellent work!

Thank you so much for your videos

This pattern has been around for longer than I have! I know what you mean, how did they tie these in the pre genetic hackle era. Something else I learned a few decades ago was wrapping hackle over a dubbed shank made everything stand up even straighter. Doing this I accidentally created one of the best Arctic Grayling flies I had ever used. I put a medium green Seal-X on then wrapped my hackle. I tied a lot of that type of Bivisible for friends for many years. You did a great job of showing this pattern being tied. Thank you!

Great tutorial!! Loved the music!! Thank you......

Nice and good job!
