Great fly! Sometimes if my Marabou blood quills are long enough, I leave the chenille out altogether. The marabou body will undulate much better. Of course you have to have extra select marabou blood quills to get them long enough. It does make a great body. Of course then I also put a sm. ultrawire wire to reinforce the hackle and the marabou. Try it, you may love it. All the best, Sean
