Years ago I started tying a bug I called the Crip Keeper, check out the video from 2013. I love fishing cripples during the PMD hatch as they are notorious for not being very successful at emerging. A stuck in the shuck imitation just under the surface has paid many a truck payment for me especially during a heavy hatch.
Since the Fall Baetis hatch is in full swing I figured I would tinker with the old pattern and make it look like a BWO that didn't quite make it. I have tied a few with a trailing shuck but the traditional abdomen and tails seem to work better. The wings are burnt swiss straw tied spinner style over some partridge to keep them out to the side which helps keep the profile. The wings can be a bit delicate and after a fish or two one or both of them become rather tattered or are pulled off with hemos. By putting the partridge under the wings you are left with a more traditional nymph profile once the wings wear out their welcome.
This fly has been doing most of it's damage in the riffles. That could be because thats where all the fish are right now though. I have been running it number two in a three fly rig behind something heavier like a Walts Worm, Bareback Pats or a larger Caddis Larva through riffles that are no more than two feet deep with great success.

That's all I got knuckleheads, go fish.
