Hi Jed, I haven't read the article, (mental note, subscribe to BnB) however I have been using both Poly and Braided leaders for a while now. The Air Flow Poly leaders come with a loop in one end, and then taper down to mono at the fly end. I cut the mono off and fit a braided loop to this end. It is then simple to attach to both the fly line, and the leader. I use the same leader with or without the Poly Leader, about 8' of twisted leader made from 9lb Penn S6. With this set-up, and a weighted Vampire, I have been snagged on the bottom in 20' of water with a WF6F line. My 5 wt IMX handles the line and leader set-up well. The beauty of Braided leaders is that you can cut them shorter for lighter outfits. I cut a Braided Fast sink in half, and relooped the braid. My brother has one for his 4 wt Saggy, and I use one on the IMX.
