"This weekend, I published my newest YouTube tutorial using Allen Fly Fishing hooks, the Mercury Cased Caddis. This is a very simple pattern to tie, and intended to imitate caddisflies as their cases are loose and they are making their emergence. The pattern works well, and is one that I classify as a "Guide Fly" due to its ease of tying and effectiveness on trout.
The Allen Fly Fishing hook I used is the S402BL, one that is quickly becoming one of my favorite hooks from Allen." - Tim
