Randy Diefert's Leech Patterns

This fly is called an Acetate Floss Leach.
Here are the tying instructions.
I used a Mustad 9672 hook
But, first there was allot of prep work.
Since I tye these flies in multiples follow these instructions:
Take spools of different colored Floss and cut them into 3/4" strips.
Acetate floss usually comes on 10 yd spools (The ones that I used were Danville's 900 Denier).
I used the following colors to make this blend: Wine,burgandy,black green, olive,slate,brown and a touch of Red.
After you cut all of your strips ,keep them in separate baggies and blend them in a coffee grinder in little bits at a time until you think that you get the color that you're looking for that most resemble the leaches in the lake that you're fishing. I "quality check" this by submersing a portion of the blend in water to check the color.
Once i get the color that I'm looking for I then make a dubbing rope(s) out of all of the materials that I've blended on my Dubbing rope maker. I use .060 stainless wire as the core of the ropes.
I then am ready to tye the flies.
First, Leaches are mostly found on or near the bottom vegetation and that is why ALL of my Acetate Leaches are wieghted with 10 wraps of .020 lead wire (or Substitute). I want the head to sink when I relax the fly then dart up on the retrieve.
Then I tye in the dubbing rope at the end of the lead wire and sort of taper it in. Tye off at the bend of the hook. Return your bobbin to the eye of the hook.
Wrap the dubbing rope around the hook shank towards the eye of the hook. At each wrap; stop and with your dubbing brush comb the fibers towards the bend of the hook. Try not to trap any of the fibers as you are wrapping the materials on. Stop 1/16" from the eye and whip finish. comb out remaining fibers. If you're going to fish this fly as is, You may have to slightly taper the underside of the fly to expose more hook if your dubbing rope was "thicker". This fly is step one of the next fly which is called The "Acetate Stick Leach". It has allot of movement in the water and truely resembles a leach when pulled in short 3-4" jerks.The colors are pretty realistic to the live leaches that I've encountered in many lakes.I hope you'll tye it, Fish it and enjoy it; It's one of my favorite searching patterns. In fact the only thing that surpasses it is the stick leach. The one in this picture also has a strand of Peacock herl inbedded in the dubbing rope, I like to use just a bit of Peacock herl in the stick leach pattern.
Fascinating. What an idea! Thanks for the detailed explanation for both patterns. I fish a little-known spot where big shy trout hide. I love using leach patterns on these guys on moonlit summer evenings. I have a feeling your two flies will be pure magic there.
