How to tie a Spawning Gurgler Fly for Bonefish

I recently had a request from a client to tie up a set of these somewhat unique "dry" flies for pursuing bonefish. the pattern is a mash up of Peterson's Spawning Shrimp and Gartside's Gurgler. I tied these in sizes #2 and #4 and they float really well in the dunk tests I performed. I do have plans to try out some freshwater colors in the spring for bass.
