After some tips here.
Firstly i'll state ive used a standard length long hose on twin 12s/DR classive wing and it routed very nicely.
Not im on a single tank and finding issues with it for a few reasons.
Firstly on twins it routed vertically nicely down the back of the wing and then out from under it (if that makes sense).
However on a single im finding it sticks out, comes across the wing to the waist creating a rather large loop in that area.
I dont own a can. light but have tried (i) shears and (ii) big pocket to route the hose under but it still seems to loop.
I found a photo similar to the issue i've got (its not me in the photo):

Thats basically what i look like underwater with it.
With it hog looped properly for my mouth the hose seems to have too low and below the pocket/shears so flops around and generally not secure.
Could it be something to do with first stage routing here? On twins i can route it downwards, on the single setup (apeks FSR) it routes out horizontally so is always more likely to pull across rather than down the wing.
Or maybe it works nicer on twins due to the tanks and wing being wider so hold it better?
Alternatively, am i just doing something wrong regarding routing it or is it just a little bit too long for me on single setup and i need to live with it or ditch it?
I've tried the 5ft setup and although it works i find it a touch "busy" hose wise under and around my arm.
