My vote- Whiting CDL tailig Packs http://www.bearsden.com/page610.html Many places to get it, this was the 1st shop on Google search. One pack will tie a ton of dry fly tails. Also, if you can afford it, invest in a CLD rooster saddle. Look up the color shades and order the color you want- same for the tailing packs. They do dye them. Check stocks at different shops. I got tailing clumps in orange and brown when I visited the farm last. If you don't need a whole pack, split with someone or each buy a color.
