I am right handed and it is easier to reach across with the right hand to the left side. The right side is for the octapus which routes under my arms and bungees at my neck with that new Manta quick release necklace (bungee is just as good). I do operate the spg and clip with my left hand, pony valve and regulator mostly with my right, knife with my right.
I cannot claim this arrangement as my invention, it is an evolution of many years and borrowing ideas from many places/people including right here. This is pretty much what I have come to have learned is called a Hogarthian (Hog) rig except--except, I use my faithful double hose regulators as primary and donate my bungeed secondary. I have been diving wings since around 1980 and this is my latest and perhaps most eclectic rig yet.
To be direct, I think you should sling the bottle left for many reasons including this is where stage bottles go and should you go off the deep end and go whacko and join the men in black tech bunch you will already be set up and accustomed to a bottle there (they put stages there).
FishDiver, no worries mate, the Air Buddy is still solidly in my kit. I mostly use it when going vintage as it can be hidden away easily and detracts very little from the vintage look and yet does provide some alternate air source. I would in this case, donate my double hose by twisting the hose outward as taught during buddy breathing, I would take the Air Buddy for myself--unless---the other diver is Air Buddy compliant--lol.
