All of the backplate and wing systems we sell are modular, and will work when mixing between component brands. Just because you have a particular brand of backplate doesn't mean you need to buy the same manufacturer's harness and wing.
Different manufacturers each have their own features and selling points, and like everything there are pros and cons which matter differently to different divers.
