Sub-Surface CDC Loop

We all know about the fantastic, natural floating propeties of CDC. But when you look at a CDC fly submerged, you see the hundreds of tiny air bubbles that get trapped in the feather. I showed this with a couple of earlier emerger pictures. Now that got me thinking. I have used CDC in wet flies for collars, but it's not really something I've used much for nymphs - but the trapped air gives a superb trigger to the flies -especially those preparing to ascend to surface. Hans Weilenmann's Diving CDC & Elk uses the idea. Here I have taken the idea to some of my own patterns...
