Last fall there was a nice push of chromer jacks that liked this pattern.
Purple or pink marabou tail, purple or pink estaz body, and purple or black schapplen hackle nice long and webby collared at the head and pulled back for the aero push.
Fast and easy to tie.
Also scored a nice chromer steel with the jack push. That was one fast fish. I set the hook about 50 feet downstream, felt a solid hook-up. Started to get him on the reel when I noticed he was heading to me. I pulled 2 or three fast strips when I noticed he was at my feet. He turned around and the tippet never had a chance.
