I'm using Apeks DS4's on my doubles and find that with the 22 inch backup hose, the 2nd stage just reaches slightly to the right side under my chin, when worn on a bungee necklace. Got my hoses kit from Halcyon which by default comes with the 22 inch backup hose. Was thinking that a 24 inch might route better. With the 22 inch, I cant turn my head to the left when breathing the backup.
Also does anyone use hose protectors on their doubles? I know GUE states that strain reliefs should be used but when I use them, I find that it's quite difficult to route the hoses properly with the DS4. Also i had a friend whose HP hose burst due to the strain the Scubapro hose protector put on it. I also noticed on the WKPP website that GI doesnt use hose protectors on his TX100's.
