If I didn't do so much tropics diving, I'd go for the BP/wing. Thousands of postings on the merits of these things can't be wrong. It's the simplest and most flexible design out there, period.
But I feel a backplate is uncomfortable to wear (on the surface) unless you have some suit of exposure suit on between your back and the plate. Hence my sticking with an X-Tek for so many years, and just recently the upgrade to a TransPac II. That back padding sure is nice!
Regarding the heavier weight of backplates when travelling I must remind everyone that there are aluminum and plastic backplates on the market. There are even special "travel" stainless steel backplates that have had the nonessential areas of the "plate" removed. They have an hourglass shape. I think OxyCheq sells 'em.
