I saw this the other day and I'm quite intrigued with the idea. He designed it this way to help the line go through the guides smoothly.
I also really like the idea from a different perspective; no more snipping the nail knot off every year due to the (probable?) degradation of the mono butt section I tie in. That and there isn't an injection point for water to get inside the fly line – I put superglue on the nail knot with the idea to stop this, but it doesn't seem to last long.
I've welded 3mm rings onto two of my lines already with the hope of testing them out next week.
This is what Phil has to say about his design:
"I love fishing lakes using long leader presentations. For years, loop-to-loop leader connections have made these presentations challenging. We now have a solution. As a devoted stillwater fly fisher, these Ambassador lines are a game changer, making long leader presentations a breeze. The smooth leader-to-line connections of these lines slide through my rod guides smoothly, not only when threading the rod and preparing to cast but, most importantly, allow me to bring long leaders into the rod without binding at the tip to land fish efficiently With loop-to-loop leader-to-line connections removed, on-the-water line changes are now a breeze. Having these lines in my kit bag gives me a critical presentation advantage."
