I have an older DSS backplate and doubles wing that has the cutouts for cam bands for independent doubles.
I decided to try this configuration for two dives a couple days ago. First dive with two LP72s, second dive was a night dive, and I swapped out one of the LP72s for an LP85:
I used SPGs of contrasting color and size. The larger one with the white background is my usual SPG, and was on the right post, and the smaller one with the black background was on the left post. Other than the extra SPG, the assignment of hoses to posts was DIR.
The configuration dived well, with several practical benefits over banded manifolded doubles:
1) No need to dedicate cylinders to a twinset, can dive singles when appropriate and use the same cylinders for doubles
2) Can swap out a single cylinder after a dive if that makes sense under the circumstances
3) Could use rental cylinders without having to seek out a shop that has a twinset for rent
4) Easier handling of cylinders for transport and filling without the weight and bulk of a twinset
The main drawback that I encountered is that the process of attaching the cylinders was somewhat awkward compared to either a single cylinder (where I can lift the BC with one hand and handle the camband with the other) or a banded twinset.
I am not sure whether I would be comfortable with a single camband securing a larger cylinder (e.g. HP120) in place.
