So I watched, your video, it's a stellar effort. It takes a lot to put something like this together, so well done OP
@roman50
I have only just started my SM journey, so am absorbing as much as I can, but have a fair amount of 'other' dive experience. Although definitely NOWHERE near
@tbone1004 at all, that's for sure. Sho!.....anyways, I would be listening to the gentleman's comments, as others experiences may just cut your learning time.
You asked for feedback, and I think that is exactly what you got. There is nothing wrong with trying things out, but one thing mentioned here was 'open mindedness' and I think if anything that is the key. To consider most opinions, and try things out that make sense. I think the reason you have perceived so much here as 'negative' commentary, is because of the lack of open-mindedness. Not everyone is right, and even those that are, may not be 100% right, I get that. They also may not know your specifics, but all I am trying to help with here is for you to consider some things that have been said.
Again, I am new to the SM seen, but old to the diving seen. And personally, just observing your techniques, it seems very task heavy as already mentioned, and excessive. I think the thought path is great so well done, but you may find ways to simplify this even more, whilst still making it safe.
We primarily dive off of RIB's here in sunny SA, and I think most will know that we definitely have some serious waters to contend with. I often have SMs on boats with me when we are doing tech dives (and rec dives of course) as we are a mixed bunch of back mount and SM. And most of the time they will clip their gear on correctly and have everything set-up 100% before entering the water (we do also get kitted up at the site with cylinders, short or long boat ride, regardless). The only change may be that they have clipped off the top of each tank with a double-ender from the shoulder D ring, to the thin rope we tie around the neck of the cylinder. Then once in the water, you can bungee up. This is also a nice fail-safe if your bungee does snap on a dive, then you can still clip off the cylinder. You can also use the bungee initially, but this is a bit of a 'save-the-bbunge' trick.
Another bit I have done with a stage before, and was a suggestion from my tec instructor, is that if you do want to re-clip something/roll back off the boat differently etc. then clipping the cylinder to your crotch strap might be better as it sits between your legs and is easier to hold on the backward roll, even when holding other items. Its just another method to try, that's all. But more applicable to the 3rd (stage) cylinder more so then your back/side gas.
So basically what I am saying is, we may have the same struggles you talk of re environment, filling cylinders etc. or maybe even worse, and we still find ways to do it, that from my 'limited' knowledge and observation seems a lot safer and easier. I really think what's been said here is only in the positive sense (except maybe a comment here or there, I didn't read all) and are intended to help you become a better and safer diver.
Good luck, your photography and videography work does sound super interesting
