It seems like the Dive Rite wings are almost too open and would move around too much though I may be wrong. Looking at some of the Hollis wings I wonder if they use wide slots, they look wide in the online pictures but as there are no retailers close by I can't just go in and check them out. Specifically I'm looking at the C45, even though it's supposed to be a doubles wing I see a lot of people use it for singles especially with 8" tanks.
