Humuhumunukunukuapua'a:
I'd definitely like to hear of your experiences. I'm just a hair away from ordering one of these puppies.
ok, here goes:
I did my Search and Recovery adv. dive with it ( I'm now AOW

). I had no problems with the BC whatsoever (the problems I had were not necesarily BC-related: we went in over a rocky area and I was the only one with fullfoot fins - I got myself a few cuts and bruises

).
the bad part - not (directly) BC related:
I usually used 8Kg of lead and with a 5mm full neoprene wetsuit had neutral buoyancy; With Orion I was a bit negatively buoyant (almost breached the surface a couple of times). Luckily we were searching the bottom for a piece of lead (part of the search and recovery exercises) and once the exercise was over, I was able to put that in the front pocket of the BC; it was
perfect from then on.
Also while exitting the water, I had a bit of a problem and my buddy tried to make sure I was positively buoyant: he grabed my power-inflator and over-inflated my BC and I ended face-down in the water with the reg. off. I almost had a good drink

.
the good part :
It was my first experience with both back-inflation and weight integrated BC, and
I won't look back!. The fit was great, and the BC is very confortable; You also get no squeeze around your body when you inflate it. Position in the water was perfect, and on the surface it's good, as long as you don't over-inflate it.
I used 9Kg of lead: 1 each in the trim pockets, three in each dropable pocket (althow the manual said they were for max. 2kg each), and one in the front pocket - which I added later, while underwater. The dropable pockets are easy to use and easy to pull out. I had no problems with them.
I also read someone saying the tank straps tend to loosen a bit; I had no problem with this, but I made sure to tighten them as much as I could (due to that warning). They have a label on them saying to make sure they are wet before tightening them, as they tend to loosen when wet. I didn't wet them and still had no problem.
[edit] I also have a crotch-strap - I bought it since it's cheap and specially made for this BC, but I didn't see a need for it.
My instructor said it's a good BC (very good value for the price). He also advised me to make sure I don't forget to open the chest-strap before trying to get the BC off: if you forget, it comes around your neck and it's not a pleasant experience
