After perusing the ‘website’ and watching their vodeo, I have to disagree with those who think they are intentionally ‘snagging’ the fish, as I understand the term.
From what I can tell from the site, they aren’t watching the fish and then pulling to hook them, they are getting the fish to strike their ‘fly/flies’ then setting the hook by pulling the fly ‘out’ of the fish’s mouth and the hook into the flesh at the side of the jaw.
From the content, it seems like their focus, other than the obvious monetary one, is to make it better for the fish, i.e; easier to release. Much of what they write and show is stuff about keeping hooks out of the delicate internal oral cavity tissue and the resultant harm and/or difficulty in removing hooks from such an area.
Since I believe that they are championing the cause of ‘catch and release’, whether or not the law requires fish hooked in such a manner to be ‘released’ is a moot point, as is whether or not it ‘counts’.
From just my first instinctual reaction to their ‘system’, I’d think this would make it harder to catch fish, rather than the reverse. They are counting on the fish getting the line into it’s mouth and the line remaining there while the angler ‘strikes’. Things could go wrong, like the fish turing away and line coming out of the mouth, the hook ‘missing’ the fish’s jaw, etc… They are using a circle hook, so if it doesn’t hit the ‘jaw’ edge, it won’t hook the fish…
They also claim that you can use a brace of flies with only one hook at the ‘bottom’ of the rig…again, this means that to hook the fish that hits the ‘top’ fly, you have to pull the other flies AND the line through the mouth without the fish reacting is such a way that the line leaves the oral cavity…not so sure about that one.
One concern I have is the line and hook catching on the front fins. If the fish keeps moving after the strike, the line could lay alongside the fish, and a circle hook can catch on the fin/body joint…
All in all, though, if you are concerned mostly with the health of the fish and not about how many you actually ‘land’, this may be a helpful concept.
I am curious about the idea of flies tied on something other than hooks or tubes, though. The idea of tying a size 24 midge and still having a size 10 circle hook in the fish is intriguing. As is the idea of fewer tangles in multi nymph rig…
Like many things, it will have it’s adherents and it’s detractors.
As far as legal or illegal, it would take a picky warden and a heartless judge to issue and convict for this system. It’s not just about the ‘letter’ of the law…
