This is how I felt reading that wall of text.Looking for "critics", huh? You've come to the right place. But here on the internet we call them "haters" or "trolls" instead of critics.
I think that if I could summarize your next major hurdle in a compact phrase, it would be that you are too strong for your own good. Your normal roll comes around really fast, but I think that part of that is because you are muscling it a little. Similarly, on the bow plow, you are strong enough to make it work. Personally I am not a fan of the bow plow, and I do not teach my students that technique. The double pump right near the end (2:40 or so) is the technique I have been teaching to spencer. You have enough arm strength to get some results, but that's the exact problem. The motion should come from your core. Use those abs to get the boat sort of hopping, and it will not take very much effort.
I like McCrotchen's description, but I would tweak a few things. On step 2, lift your bow up (higher than you are right now), but do not commit your whole body to the motion. While the bow is still on the way up, start sitting a tiny bit more forward and trying to sort of jump up onto the bow end. Basically, don't wait for it to stall out before going to step 3, do it very early. The key part of step 3 is that you are turning to face the water. This can be hard because your paddle is in the wrong place; it's still vertical in the water. You probably feel like you want to just keep pulling the stroke through until it reaches the surface and leaves you in a perfect wound-up position to throw the bow, but that will not happen. There is too much water in the way. Get your blade free of the water by just sort of picking it up out of there sideways. Rotate your shoulders and belly to face straight down toward the surface of the water, and put your paddle blade on the surface, ready to throw the bow down (you might hear a slap as it hits the water if you're doing it right). While you've been doing this, your bow will be getting about as high as it can get, and starting back down. Now, your blade and upper body are rotated into a very powerful position to throw the bow down underneath you. Use your abs and think about pushing your feet around. Try to make it look like you're just doing it without even trying. Your upper body should more or less form a sort of box, with shoulders and paddle parallel to the surface, which will stay stationary while the boat rotates underneath you until it's vertical.
In the video, you wind up but your blade stays in the water a little, and more importantly your core stays facing forward, so when you try to push the bow down, you run out of stroke and have to straighten your arm, which rotates you around the long axis of the boat, onto your head.
Furthermore, don't worry about practicing the roll too much. If you're working on the cartwheel correctly, you will flip over all the time. If you stay upright, use more edge. If you enjoy it, go for it, but if you are practicing the roll because you think you have to, switch to something you enjoy. And I agree with dirtbag wholeheartedly when he says not to listen to himself.
