Regarding the wing in the video:
I have never heard of this brand. Having spent time in the Halcyon factory recently, I can tell you that their stuff is made literally on-site and beautifully... When you see them being made and welded ultrasonically, you can definitely appreciate the quality in workmanship even more. I can also tell you that their lifetime warranty is absolutely phenominal... I purchased a Pioneer wing more than ten years ago, and have replaced it - free of charge, and at one time actually receiving an upgrade to the Eclipse - at least four times. While this sounds like a terrible review on Halcyon quality, nothing could be further from the truth... For me, that's every 750 or 1000 dives. In all fairness, things DO wear out, after all.
Most people will never approach that many dives in their lifetime.
Having said that, I can tell you that a 30 pound Eclipse wing costs more alone that you have spent for your entire BP/wing package. Like I said, I think it's worth it, but... That wing there looks like a clone and I'd be very interested in seeing it's level of durability over time and how it compares to a Halcyon.
...So +1 on the wing. Let's see how durable it is and if it can compare.
Regarding the size of the wing... Your dive shop has steered you right... Most singles wings are nicely tucked yet offering a good amount of lift around 30 pounds. A 40-pound wing is better if you're diving a drysuit and/or with larger steel tanks. More on that later... You did great with a 28-pounder. +1 on the wing size.
The STA looks like a standard STA. I'm a big fan of Oxycheq's "Scott Koplin" designed STA that is hourglass-shaped, but I honestly can't say that it has any advantage over this standard Hollis/Halcyon/Dive Rite/OMS design... I just like the look of it better. Either way, you did well on this purchase too. +1.
The stainless steel cam bands that hold a single tank to the STA are FANTASTIC. There's only three cam bands that allow the cam band to completely come apart when you release them, giving your rig the advantage of being able to change your tank with the rig laying down on it's face. This is a huge advantage on a rocking boat offshore... Simply lay our rig down, pop the two releases and unscrew the first stage and swap. It's much easier than trying to do this with the tank standing up, and does not require that you remove your regs from the rig... So the process is waaaaaay simpler, safer, and easier. People on the boat diving with you will be jealous.
For what it's worth, there's only three cam bands on the market that do this... Scubapro cam bands, these generic cam bands (both of which are almost identical designs) and Highland cam bands, which are a completely different design. My personal favorites are the generic ones that you have there, but I'm not a fan of the white-striped cam straps, so for me, I use only the Scubapro cam bands, modified to work like the generics. Any one of the three enable you to change a tank like this, and you have one of them on your new rig, so a big +1 on a subject not normally even noticed by gear hounds.
Regarding the backplate, I feel that you'll quickly move from an aluminum plate into a stainless one. The difference is that a stainless plate is 6 lbs negative, whereas the aluminum one is less than 1 pound negative. There's a lot of factors that go into weighting, obviously, but the real question is... "How much weight do you use as a minimum?" If you're the kind of diver that dives in a T-shirt and bathing suit in a pool, then an aluminum may be for you. If you own your own steel tanks and find yourself overweighted when using them, then moving to an aluminum plate may be the ticket... But if you're using the every day aluminum 80 tank and/or find yourself diving in a wetsuit even in warm water (which I always recommend - they keep the scrapes, bruises, bumps and stings off even if you don't need them for warmth), then you're better off using a standard steel plate. Steel plates take 6 lbs off of your waist and place it over your lungs, which dramatically improves trim characteristics while getting lead off of your waist. The only reason you wouldn't want this is if you were overweighted at six pounds (like you actually needed LESS than that), or if you were using heavy (and less common) steel tanks that were already very heavy. So... A -1 for your choice of backplate materials unless you're a "bathingsuit only" and "warmwater only" kind of diver who would not benefit from having 6 lbs taken off of their waist and placed over their lungs.
Harness: Yes, I know that those harnesses are being sold as "deluxe," and that they are considered an upgrade. However, it has been my experience with regards to harnesses that "less is more." Like a running shoe vs. a work boot, less feels better and is more streamlined and allows for easy customization, a simpler setup, quick and inexpensive replacement, and an overall advantage over the "deluxe" harnesses. Yes, I know, the dive shops all say that "deluxe" harnesses are better because they have padding and chest straps (that get in the way and don't actually have any advantage) and plastic doofangies and quick releases (in case you want to quickly separate you from your life support system?), but in my experience, they aren't. Padding only gets in the way at depth, and on the surface, a neoprene wetsuit is much better padding than any fluffy wet junk on the rig itself... The wetsuit is like "gel" padding. Plastic doofangies and quick releases only age and break (like I mentioned before), and chest straps are annoyingly in the way and usually get cut off by divers anyway. Mostly, however, "deluxe" harnesses do not allow for infinite adjustment of D-ring attachment points, which is to say that you'll quickly become annoyed that you can't place the D-rings exactly where you want them... You'll be kinds stuck with where the seamstress chose for them to be... Which may be adequate, and may not. So... A big -1 for the "deluxe" version of the harness.
Crotch strap: The whole world is using a 2" crotch strap with both a P-ring ("scootering" ring) and a butt ring (similar, but on the back of the crotch strap), yet I repeatedly see new companies coming out that use either 1" wide webbing or 1.5" wide webbing. I don't know why the manufacturers keep doing this... A soft 2" crotch strap works great, even if you're clipping into a scooter and it's pulling you around by the crotch strap. 1" crotch straps give wedgies if you try this, and 1.5" cortch straps are predictably somewhere in-between. The crotch strap on this system is a 1.5" strap. I don't know why they'd do this, but I see it regularly, and no, 1.5" webbing is NOT cheaper than 2" webbing. My recommendation is to change it out when you get the system so that you don't wedgie, especially if you're wearing a bathing suit only. Yes, that's a visual. Uaaaahhhhh...
Next topic... -1.
Now... Here's the cool part of a BP/wing: Get what you've ordered and try it out. If you choose to change to a steel plate or a simple (or "Hogarthian") harness system, or a 2" crotch strap, then you can... Simply order the part and take the old one off and put the new one on. It's that simple. Or don't. It's up to you... No engineering degree necessary. If you can tie your shoelaces and adjust the buckle on a baseball cap, you can replace/change/adjust anything on a BP/wing that you want.
Hell, you could even add neon pink webbing and plastic quick releases if you wanted to...
Not that I'd recommend that, of course... Please allow me to introduce you to the unofficial joking concept of "Rule 6."
