How could a group as paronoid about oms's bwod allow their followers to dive a piston reg. If you open a well used piston you will see the ambient chamber is almost always coroded, the ip chamber is also. The piston o-ring is often not in the best shape, in fact it is on its way to being extruded! Scubapro also claims the highest flow 1st stage, but all that means to me is when you hp seat going and everything starts free-flowing you will be empty in a matter of seconds. Is there somthing I am missing?
