I'll add my 2 cents. It appears that you are using the long hose on the left and short hose right. I know of at least one instructor that teaches that hose routing, with the suggested advantage of better hose routing. As I understand that approach, the short hose comes directly from the right tank to the regulator (on a necklace) with a 90 degree adapter; not around the neck. To further keep the right hose close to the body, the right hose is routed under the chest strap. The long (left) hose is mostly stowed on the left tank and comes up the left side and around the neck. I have not tried this and use the opposite routing as I like to remove my right tank to get back on the boat, allowing me to keep my BC inflator attached to the left tank. Your regulators face each other, you may wish to try having your regs point down or point up. My tanks are pulled up tight into my armpits, so even with the regs straight down and valve handles straight out to the sides, there is not much hanging below my body. I was experimenting in the pool today with the regs up to try and streamline even more, but I still prefer regs down. The valve and regulator position is controlled by the tank cam band.
