Ok, as you have the tank on, you have a right post over your right shoulder and a left post over your left shoulder. On the left post is your brass SPG (24-26" hose; no console; clips to left D-ring on belt), back up reg (unbalanced; 26")which goes behind your neck and under your chin, and dry suit inflator (24-26") which routes under your left arm pit to your chest. Ok, a little more on the dry suit inflator, if your inflator valve doesn't rotate to the left and is stationary to the right, you will have to buy like a 30" hose and route it behind your neck and under your right arm pit. My valve rotates on my suit so it goes under my left arm pit. The other option would be to take out the existing valve and turn it so it faces left. I'd opt for another hose.
On the right post is your 7' hose which runs straight down and can be "hooked" by your knife or shears sheath or cannister light, or tucked inside your waste strap. The hose crosses your body and wraps around the back of your neck and goes in your mouth. It has a bolt snap at the second stage for clipping to a D-ring when not in use. Then you have your BC inflator (24") which crosses behind your neck and down to the inflator. You can use some bungie to keep it tight to the inflator hose (the Halcyon has it on there already).
That's it. The first stages lay horizontal and the hoses point downwards. Everything will line up just fine. Make sure they have hose protectors on each hose at the first stage.
One last thing, don't place too much confidence in the dry sealed first stage. I have the Zeagle T-50D which is identical to the Apeks, and I have had several secod stage free flows with the reg in water temps around 32-36F. I've talked to many others who have had similar problems.
Later.
Mike
