I use a 40in hose with an 90-degree
Angle Adapter on my primary (I got mine from Trident). The hose goes out your first stage, under your right arm and into your mouth.
I DO NOT use or recommend ever using a
Swivel. There's a slight difference between the two, the main ones are:
- Angle adapters have 2 connections between the hose and your second stage where as Swivels have 3 connections.
- Angle adapters only use the proven standard hose connections couplings
- Swivels use standard hose connections plus the Omni-Swivel
- Swivels have been known to separate and catastrophically fail at their Omni-swivel
I get this out of the way because there's a misconception between the two.
I choose not to use a 5ft or 7ft hose with the Hog wrap configuration because in an OOA scenario there's a big chance for me to hook a long primary hose on my integrated pockets or on my finger spool which is kept on my hip D-ring.
When I eventually get the money to "upgrade" to a Bp/W then I'm looking at a 7ft hose.
Reason for this is because I've heard a 5ft hose interferes with your Right Shoulder D-ring at times.
The main reason for getting a longer hose for me though is because I use a bungeed backup, I absolutely need more length for an OOA situation. The main reason I choose to upgrade to a 7ft hose after getting a Bp/W is because my angle adapter likes to clang on my Bungee backup. And sometimes it will even lightly hook onto the adjustment dial of my backup's second stage if I turn my head in a certain pattern.
My current BC however makes getting a longer hose even less ideal IMO.
YMMV
