    Honestly - there’s no real need... the hoses look tightly bent - but they’re fine...

    As Paulo says you can angle them if you want - I sometimes put a very slight angle on them but it doesn’t really make much of a difference

    I have little 90į adapters on mine.

    I don't know which brand they are - ESM most likely.

    I only use them for strain relief on the LP hoses because I didn't much like the look of the sharp bends but whilst you're actually in the water they don't make any difference.

    Some 90 degree adapters drop the reg performance quite markedly especially at depth

    I think that they pretty much all do. However, very much like the theoretical loss associated with a long hose, it doesn't seem to make any difference in practice.

    I think itís a bit more than theoretical if itís measurable. They are fine for tidying hose runs for suit feeds and the like but I wouldnít put a 90 degree swivel fitting on a hose supplying gas to a second stage.

    The difference is of course measurable - my aqualung legends have failed the en250 test on an Ansti machine allegedly due to one or both of the adapters or long hose (they've also passed in the same configuration).

    There's a loss, but in practice it doesn't seem to make any difference.

    As the author of the blog Iím pretty sure Iíve never had one in all my time of diving. Same could be said for the 180 degree on a stage SPG.

    PS. I started with the left reg left shoulder. Soon changed it; read into that what you will. But itís a 2 min job if you do decide to do it.

    I used the std DSTs for a while, but switched back to DS4s - you dont need the 5th port on the DST - just set them up as tehr DS4s are here http://rectotec.blogspot.com/2015/01...egulators.html
