The only way to cant the O2 cylinder is to rotate the reg 90 degrees which points the hoses straight out to the side. There are two options - you can either use adaptos, which I did, or bend the hoses upwards. I didn't like the bend the hoses option because inflating the wing torks one of the hoses. Hard to explain - easier to see in person. Also one of the hoses in this configuration gets in the way of manipulating the O2 valve handle a little bit. I suppose buying a new reg is a third option, but then I'd have the expense of buying it and then would have to convert it to work for the COPIS.
Good points, but I don't mind the added o-rings - although I'm sure some people would.
This was the easiest way to configure it how I wanted.
Why cant the cylinders in the first place? Because I find them to be a pain to put on when they are straight due to the low clearance of the shadow gear. Love the shadow gear though.
