Sorry I didn't answer your question, but I didn't have any pictures and what I use for tarpon is a no-slip loop similar to the Lefty Loop but a modification of it that I've been using for about 2 1/2 years and am now very confident with since it has been proven itself on large tarpon and much smaller saifish as well as a lot of very strenuous manual break tests.
Those comments above were not meant for you, by the way, GB, but for guys not familiar with salt water, bite tippets etc. Only this knot itself might be of interest to you, and perhaps a few others here.
The Lefty Loop is a great knot, but I am paranoid about picking up bay grass and other stuff so I do it differently and it is complicated to explain. But far easier for me to do than the Orvis knot. It's odd, but some knots I can only tie with the hook in my right hand and others only with the hook in my left hand. With the Orvis knot, I can never remember it for one thing, and when I look at the animations, they are holding the hook in the wrong hand and I can never figure how to switch it. Besides I am one hand short for that knot I'm afraid.
Instead of a single overhand I start with a double like a surgeon's loop 6 or so inches up and snub it enough to make the 2 little loops that stick up on each end like a figure 8. I then pass the end through the hook eye and they through the two little loops following the same path as the standing line. I always keep these little loops facing up not down from here on. I slide the figure eight right up to the hook eye. This way, when complete, the loop is not gargantuan.
I now have the standing line and the main line parallel and I squeeze the two flat right next to the the figure 8 loop away from the fly. In my case, the tag end will always be away from me because of the direction I always go when tying a surgeon's loop. If someone else is doing it it may be towards them.
I now slightly spread the main and tag lines slightly between thumb and forfinger , keeping them both in the same plane without twists. I then wrap the tag around the main line going AWAY from me as it crosses the top of the main line. If the tag were on my side of the main line (again, hook in left hand) I would wrap towards me as the tag goes over the top of the main line. I would wrap it 3 1/4 times then pass the tag between the standing and main line coming up from the bottom
and then directly through the two little loops at the ends of the figure 8 towards the fly.
Then I cinch up the figure 8 portion of the knot while holding onto the original two parallel and horizontal line coming out the figure 8 loop on the side away from the fly.
Now I cinch it up with a hook ring (or improvisation) pliers and the other hand. The bite tippet, if you are doing the IGFA thing is always put onto the fly first, then the class tippet is attached to it. What you wind up with is pictured below, tied with 60 lb flluoro. The standing line winds up running very straight into the loop, and the tag will not pick up any ****. If the wraps are not done in the direction I indicated , then the knot is what will look like **** and probably be **** too.
Since neither my buddy Apple or I have ever seen or heard of it, he dubbed it the Cnut loop in keeping with the double nut squeeze, leader to fly line connection. I have bent up the tag to make the knot orientation more obvious.
