Looking at the way the stream is set up I would fish from down stream and throw a Renegade #14 with a Copper John dropper in a size #16 or #18. I really like red and green Copper Johns, or I believe the are called Serendipity which looks very similar to a Copper John with a CDC. I would definately work the obstructions and deeper runs, along with running under the over hangs.
