Welcome to the IGKT and I hope you hang around, you are like a breath of fresh air (and by the looks of your YouTube vids a totally crazy character to boot).
I am a great believer in using and re-using the simplest of knots, and your novel use of two slipped OH knots is a little gem. It is so logical, I am sure it must have been 'discovered' many times over by folks fiddling with rope, so I am amazed that it does not seem to feature in any of the usual reference lists, but perhaps someone will spot it amongst the thousands of images in ABoK, not that that should detract from your discovery (or rediscovery if a reference to it is later found).
Is it a knot or simply a use of the slipped OH? Of course it is a knot, just as much as a Sheepshank or a Matthew Walker is, but instead of calling it the Positive Knot, perhaps a more memorable name would be 'The YANK' (or should that be OGNANK - Oh God, Not Another New Knot).
As for 'is it a good knot'? that is an all-together different question.
Is it easy to remember? -- Yes, based on the simple slipped OH -- 10/10
Is it easy to tie? -- ditto -- 10/10
Is it hard to get wrong? -- Yes, two slipped OH's and it doesn't seem to matter which loop goes through which -- 10/10
Is it possible to dress it wrong? -- not tested it enough yet -- ??/10
Is it stable? -- ditto, but so far looking good -- ??/10
Is it strong -- the tight two diameter loading loops will probably be limiting, but it is likely to be as strong, if not stronger than the Bowline -- (5/10 as a guess)
Is it easy to untie? -- in light to medium loads, yes, in overloaded or problematical cord possibly not -- 8/10
Am I going to use it? Yes, I will give it a try, but my preferred loopknot is at present the slipped OH tied using a bight and the slipped end loop either passed forward to make three loops or passed over the main loops and back around the SP(s) to form two loops. For example, if I am tying down a load, I can use all three loops to form Z loops in three different directions to strap down the load and the whole thing auto adjusts as the tension goes on.
As for video vs diagram, I understand Roo's position, so here is a diagram for those who don't have a connection that lends itself to viewing video clips.
Please let me know if I have it wrong !!
However, video is without question the future for all knot knowledge transfer, explain and show at the same time - how to tie, how to dress, how to use, how to untie - it is the perfect media and your video is excellent. So good in fact, that I have to ask a favour of you.
Would you consider making a short tutorial of 'How to make a video of knot tying' - what camera quality/options, recording format/quality, lighting, focus, sound, how to format it for YouTube etc. etc. -- PLEASE.
We are lucky that you have stopped by, crazy folks like you are likely to be the only future that knotting has of becoming a popular activity again. I can tell that you are a knotahollic from your dexterity in handling cord and the way you automatically use twist to form loops and remove twist as you dress up the knot. Excitement, energy and interest like yours is infectious and your love of knots and cord will undoubtedly catch on with others of your generation - provided you live long enough that is - was that you riding down a rocky hillside on a one wheeled bike
