Just put my first doubles together today and Im wondering if everything is correct. I have two DST's so I just decided to use those instead of selling them and getting DS4's. Any comments or suggestions would help, sorry if the pics arent that great, just let me know if I have to do something different/better, Jared
I would say that you should not cross the inflator hose over from the right shoulder post. Just place it on the left shoulder 1st stage and run it down. But its most likely too long, you would need a new hose. When moving to doubles it gets expensive, b/c new hoses are often needed to optimize and everything should be as simple and streamlined as possible.

It's one very common practice to route inflator hose from right post (and drysuit from left). Another one is to do it from left. Maybe we should ask why OP is doing it from right before stating "should".
From the pic I can't see much of the left post but the gauge looks like it's routing from the other room!
Edit: Ups, I was able to see only the first picture initially...
Usually, in cave diving, we route the inflator hose off the left post and the dry suit hose from the right. We use a 15" inflator hose and 12" corrigated hose for the inflator. With it on the left post, when you go to use the inflator and don't get anything, it makes you aware you've had a knob roll off.
The left side is the "roll off" side and the right side it the "roll on" side (from the knob standpoint) which is why we always put the long hose on the right side (which is the way you have it!). The long hose is the one we donate to an OOA diver and you don't want it to be a quarter turn from being off if you bump the overhead.
I see you are using a console. Tech divers usually use just an SPG, and have a wrist mount computer, but what you have looks fine.

My only comments are from your equipment in general. The primary is either in a mouth, in your hand, or clipped off on your right chest d-ring. Move your bolt snap closer to your primary and tie it off that way, when you clip it off, you know exactly where it is and not fiddling with the extra foot of hose that your regulator is dangling from. And finally in these points, maybe shorten up the hose on your computer if you elect to continue its use and then attach it to your left hip d-ring with a bolt snap.
And really finally, you asked if everything was correct but Cave Bum gave rationale why it is the way it is. That is the most helpful.
Good luck!
With kind regards,
Thomas

I would take the DSTs and turn them into stage/deco regs.
Get some DS4s for backgas, the hoses will stay put then.
For me:
Primary inflation (wing) goes on the right post so it can't roll off.
Suit comes from the left post or side if using an argon bottle.
Hoses look about the right length maybe a few inches too long but its hard to tell.
Swap the HP hose for something 24-25" long.
Swap the console for a simple SPG.
Put a boltsnap on the SPG to clip that off with.
Put your bottom timer or computer on your wrist.

Why would you cross hoses? Where's the benefit? I do almost exactly what cave bum describes (slightly longer inflator @ 16").
I am guessing he is doing it from right, b/c his hose is too long to run from the left post. It really shouldn't matter in most open water cases, but since he is running an AI console, I also assumed that he is not getting into any significant tech diving. (As some instructors would make him get an SPG and wrist thing.)
I think having the hoses set up as simple as possible is just more efficient. It was my suggestion.
The main reason I can think to not run from the right post, is that is the post that is doing the most work, and therefore is most likely to enter into a freeflow situation. Usually turning that post off is pretty easy, but then you turn your B/C supply off too; same if your buddy turns your manifold off. Most doubles divers don't wear weight, and therefore would be in trouble. But usually this only happens in cold water...
But really it doesn't matter that much either way. It gets very expensive and takes alot of training to place in a complete redundant system. Dual bladder inflator, two computers, pony bottle set with a proper pp02 to match the deepest part of the dive, lift bags, reels...
I don't like the looks of those sharp bends in the inflator and octo. Do those monuts swivel or are they fixed? here are some pics of my CDX5 regs. It if your regs are not well suited for turning sideways then there is no reason to do so. I have since these pics were taken though moved all the hoses to the back ports. They route even better.

Putting the wing on the left post means it can roll off. Its your primary buoyancy device and needs to roll "on". If your suit (on the left post) rolls off its no big deal, you still have primary buoyancy, just stop your descent with your wing and turn the left post back on.
Other reasons for the wing inflator on the right post:
(1) Allows a second "regulator" in case the left post fails (you could donate the long hose and breathe the gas from the wing; certainly not ideal, and certainly not likely, but a benefit nonetheless since it would not work at all well if placed on the same post as the hardly donatable necklace).
(2) For those diving in cold waters having to deal with the possibility of a freeflowing inflator (which can cause freezing, so that you can't just pop off the LP hose), having the inflator on the right post allows you to shut down the post feeding the wing (right hand) while simultaneously dumping the wing (left hand), while swimming down to maintain depth. This is quite doable (we had to do it in our T1 class) and a buddy actually had to do this once for real.
