Glenn, SRC are aggressive feeders and will attack almost any fly when they are present. I like angel hair baitfish patterns with epoxy heads, the Knudson Spider, Johnson's Beach Fly, Jim Dandy, and Leland Miyawaki's Popper. Les Johnson's book, Fly Fishing for Coastal Cutthroat Trout has great patterns and info that will shorten the learning curve on SRC. Also, Pugetsoundflyfishing.com has a great fly archive that has lots of good patterns. Most local fly shops, particularly Puget Sound Fly Company and Patrick's Fly Shop have great saltwater selections. I would guess that the NW Angler Fly Shop on Bainbridge where David works has great SRC flies as well.
Good luck. Steve
