I just sat down and tied it. I've never used this specific fly. The nice thing about fishing for searuns is that most of the time it doesn't really matter what the fly looks like. I try to tie flies I like the look of. I've caught them with a brown wooly bugger but I'd prefer to catch them with something a little prettier.
Looks a lot like an amped up Gartside Soft hackle. I like yer version a little better, especially with the pearl colored body. Did you prop up the marabou at all?
