New Weights ~ BH Biot Trigger Nymphs 26Mar20

While leafing through Mercer again I saw the PMD Trigger and decided to tie up my variants as an alternative to Rainbow Warrior and Black Ice as my weighted top mayflies. It's early to tie PMDs but I was intrigued and have been experimenting with dyed turkey biots. Here are the PMD and BWO variants...

• Hook: #16/PMD & #18/BWO TMC 3769
• Tail: 3 PT fibers ~ bronze side/PMD & olive side/BWO
• Thread: Carmel/PMD & Olive/BWP
• Bead: 2mm gold tungsten/PMD & 2mm black nickel tungsten/BWO
• Body: Turkey Biot: Rusty/PMD & Olive/BWO
• Thorax: Tan UV2/PMD & Olive/BWO
• Wing/Legs: Hungarian partridge feather fibers
• Thorax Topper Attractor Flash: PMD Ice Dub/PMD & Olive Ice Dub/BWO

The trick (beyond tying with biots in general) is very sparse ice dub lifted above the base thorax and then squished down the thread onto the the top of the fly - then whip finish. It's called a trigger because the ice flash should trigger a fish response.
