The way I see it, at the core of it is the desire to have as little surface area exposed to water density as you want to move. Or not to be swept away by underwater currents.
The wing system has air and most of the bulk (plate) in the same place and it is at the top of your center of mass underwater (your mass together with tank).
And the weight pockets are in the same place in jacket and wing system - on the belt area. In case you want to dispose them, or hand over to someone before you give them the rest of the gear when coming back on the dingy.

@Giles said in Scuba anyone?:

XDeep Ghost ordered for Paula......

It didn't take too much convincing, has it?

@Giles said in Scuba anyone?:

One of the girls in Raja dived sidemount. She always looked so at ease and streamlined under water. She was just diving with one tank.....

It's possible, I had 2 guides in Egypt for last few years that were doing so. All their weight was in the opposite wing pocket from the tank. And as tank you can use normal 12L. But sidemount is just really flexible. Even when diving from the boat, people will even go with two 15L for a longer deco dive. And maybe additional 2-3 L for 50% nitrox for deco, or even oxygen at 6m.

@Giles I need to consider this. I had few occasions where I shared air with other divers via my main long hose. In this situation I would have to use the inflator during the dive in the double role, right now I have the same 2nd stage on the necklace. In the cold waters I find myself in that could be risky. But in the warm ones I can only see advantages of your setup. Less dangling thingies means less trouble at any stage of the dive.

For my sidemount rig I foresee 2x 8L, one for jacket, other for dry suit, and two equally competent 2nd stages (that I already use for years in the present setup)
I originally planned this setup for my cold-water dives, I would love to get the bottles to the water before I put on the dry suit, while diving from the shore.
But now I start to see the advantages of traveling with sidemount jacket. The weight is cut down substantially as there is no plate.

In all honesty the probability that something will go wrong with well-maintained 2nd stage is nowadays very low. I understand the risk appetite in light of shorter, more streamlined hose.

I know, but is the secret in raising the chin? You want to have the hose in the highest position. If you are breathing from it at the same time, how do you do it?

And I was looking now at the Atomic SS1 and it's a really streamlined solution, but how do you make it work when using it and deflating the wing? Seahorse position?

I was working on mine before next week's dive. The attachment that you see on the inflator is the Duck. It makes a distinct sound underwater. When you want to draw attention.
As for the trim pockets I don't really use them now, but I don't mind the pockets in case I want to add extra 1kg on the side.
