and now you're getting the biased opinions of what people have and that they like it. Hollis is by no means anywhere close to the top of the pack for quality, they are good quality, but made in China, and the overall fit and finish is not like the first three that I mentioned, neither is support over the 4th. Hollis is just one of those brands like Scubapro actually, that is charging premium pricing for stuff that is no better than products 30-40% cheaper. Sorry, but at least Dive Rite is committed to keeping their products made in USA, Nick is getting cheap wings out of China and charging a huge markup on them to pad his wallet and his marketing budget which is why I won't support that company.
For what it is worth, I don't own any Oxycheq, Halcyon, or Deep Sea Supply backplates or wings, for that matter I don't actually own any hard backplates anymore because of sidemounting most of the time. My Nomad is probably the highest quality of the sidemount rigs as far as overall fit and finish, and the wings are built like the three above, it's real damn close especially now that they have the superfabric on there, but as far as the fit and finish of the backplate itself, FredT if he's still making them *didn't list him because I don't think he is*, DSS, Oxycheq, and Halcyon really have the best plates out there.
This is all a spitting match though because at the end of the day it's a hunk of steel, and a sewn bag, they're all going to perform at a very high level. The $350 Trianta set from DRiS, err well was until a few days ago and should be down to around $300 at Black Friday, is the best bang for your buck right now if you want a hard backplate. The HOG plates are actually very very good, and the wing itself is on par with any of the middle tier wings and will last you quite a long time. It has a lifetime warranty which most of the premium wings have, and saving $300-$500 on it will allow you to get a good regulator set. You can always upgrade to a different wing down the road if you want a change.
