Ok, bare with me, but I tied these in a hurry to demonstrate a CDC wing tied in at the eye (standard) and back at the bend. The Shuttlecock Buzzer, here, was tied on a size 16 light wire hook. The body is 8/0 black thread. First I tied in two small plumes of CDC for the wing. I wrapped a tinsel body and overwrapped/ribbed it with the black thread. I spun and dubbed a small amount of synthetic dubbing. The fly was tied off at the eye, under the CDC wing. The trick is to not catch fibers of the CDC in the half hitches as you tie off.
The above Shuttlecock Buzzer is unique with the CDC Wing first tied in at the rear at the bend. I then tied in a single strand of peacock Krystal flash, then dubbed a small thorax and then wrapped the thread body back and forth a couple of times. I finished by ribbing the Krystal Flash strand up the body and tied the thread off at the eye. This fly was also tied on a size 16 hook.
Neither pattern is that crisp, but they help show the wing to the front and the more unique wing over the bend of the hook.
