I think you are talking about the Halcyon? If so, in my opinion that is the way to go. Not only are all the parts replaceable, but you can interchange parts depending on your diving. Some divers use the same backplate and harness and use different wings depending on where they are diving and their other equipment. It is also a standard setup that will work for all of your future diving no matter how far your training goes. Don't get me wrong the Zeagle is a nice unit, I just think you will get much more use out of the Halcyon (or similar) setup.
