I agree that someone asking for opinons after he or she has already opted for something is problematic. At best the person will get a few posters who chose the same option who will validate that other people do in fact choose option "X". And a subset of those people will usually have diving styles similar to the OP, but none of that has much to do with whether option "X" is really optimum or the best available option for the OP. It is argumentum ad populum support for a decision already made. But logical fallacy or not, people often find some comfort in that, especially in an equipment intensive sport like diving where, unfortunately, there is as much bad advice floating around as good advice and most of the advice one way or the other is often not attached to any logical rationale that could aide in decision making so asking after the fact is in some cases not much worse than asking before the fact.
Worst case you get 50 posts saying "X" is garbage and a complete waste of money and/or totally unsuitable for what you want to do with it. The result is you feel bad, you sell "X" at a loss on e-bay, you get depressed, you stop diving and take up golf so you can take out your frustrations by beating the bejeezus out of a poor little white ball with an iron club. The ball mocks you by slicing off into oncoming traffic on the 9th fairway. Consequently, asking after the fact posting can result in dented quarter panels, broken windshields, and angry motorists and should be avoided if possible.
That said, I faced the same decision several years ago which is essentially:
1. A transplate/comfort harness,
2. A pivot ring harness (with or without quick release and with or without neoprene shoulder strap pads)
3. A one piece Hogarthian/GUE/DIR harness (with or without neoprene pads for the shoulder straps).
After a few years of watching other divers walking along trailing nuts. bolts, screws and broken bits, I am not a real fan of anything with screws, bolts or small clips that can come loose, get lost or break. The Dacor RIG with whatever number is behind it is the grand champion in that regard (most of those divers have long since taken up golfing and discovered the deductible on their homeowers policy). To give it credit, the transplate is not nearly as bad in comparison.
I am ok with a large (2") plastic fastex quick release (QR) buckle on a harness provided you have a reason for it (for example ease of exit in a dry suit and dry cloves with cuff rings in extremely cold water/weater situations, or you had recent shoulder surgery and are still increasing your range of motion, etc) as it could in very extreme situations break or come loose. But there are three major problems. 1. They are usually on the left shoulder (where all the deco bottles get carried) rather than the right where they would be slightly less stressex. 2. To be readily accessible with either hand, they are usually mounted where the shoulder D ring needs to be in order to be equally accessible. 3. Most people who have them have no reason to have them and seldom use them making them a vestigal attachment that would be better off absent. #3 is often the case because pivot ring harnesses come with a QR whether you want it or not. If you use one, give priority to D-ring placement and live with the lower than optimum buckle placement.
The pivot ring harness will use 1" webbing sewn to the rest of the 2" harness webbing to attach the rings and despite the naysayers this arrangement is strong enough to resist anything that would not have already ripped you apart anyway. The resulting geometry and chest strap make the harness quickly adjustable if you switch from for example a t-shirt or 3mm wet suit one week and to a dry suit the next as the chest strap can readily take up the extra slack of the thinner suit. It also creates a bit more distance between straps, shoulder D-rings and armpits and is a bit more comfortable. On the downside, when your plate starts to wear on the straps, you can't just slide everything an inch one way or the other so they have a much shorter service life and they cost a lot more to replace than 10 or 11 feet of webbing. Also a non-QR pivot ring harness is not really a one size fits all proposition as the distance between the rings is now fixed and the greater thickness where the seams are will not readily feed through the slots on most plates (which is why they come with a QR and a resulting free end of strap on one shoulder). Consequently a non QR pivot ring harness is pretty much a do it yourself proposition. Not hard but you need to have a sewing machine.
Neoprene shoulder pads are inexpensive and will give you about 85% of the comfort of a comfort harness or transplate harness with a lot less expense and with the increased durability and security of a hog harness, so I am not real sure why anyone would ever go the transplate route if they have any serious technical diving aspirations - leaving the transplate pretty firmly in the "within recreational limits" category.
As an aside, I had a similar non responsive customer service experience with OMS. I suspect it may be due to them not having the courtesy to curtail internet sales, but as a bone to throw to OMS brick and mortar delaers, they do not provide on-line or phone support to on-line customers. That approach is not real helpful to the potential OMS customer who lives 500 miles from the nearest OMS dealer and who consequently ends up going with Dive-Rrite instead.
