I on the other hand loathe my backplate, only use it when I absolutely must, with twin 130s or larger, and prefer my Zeagle TECH instead, for double 100s or smaller, or for tropical dive trips, or single tank diving. The Zeagle rig will hold any type of wings as well, and they all roll up nicely, detached.
Its fairly typical, and works well, to have one B/C system for your warm water travel diving, and another backplate system for your tech rigs. You can use any one system for both, but that often presents a problem however you do it.
You do not need pockets on a backplate system, since your deco diving will be with a drysuit and these have cargo pockets. A backplate system for warm water tropical dive travel, however, leaves you with no pockets, giving you no place to put your boat diving safety gear (orange sausage, spool with 15 ft line, signalling mirror).
