I personally am fond of the DSS backplates and wings for single-cylinder diving since they allow removal of the wing without removal of the cambands.
You can have the same thing with pretty much any brand of wing, if you use ScubaPro-style quick release tank straps. Which just happen to be only $15 each on the Dive Gear Express website now.
I really like those QR tank straps and my HOG wing comes off just as easily as my DSS wing did.
I looked at some actual ScubaPro tank straps the other day and I think the DGX ones are actually better. The SP ones have the strap tail run to the outside. The DGX ones have the strap tail tucked to the inside. So, once fastened, the DGX ones cannot come loose by pulling the strap tail loose from the velcro it attaches to. The SP ones can.
