	Gil- I and my primary cave partners use both the dolphin 120s, the
	dolphin 95s, and oms 120s as doubles. The dolphin 120 tanks are 
	Pressed Steel and have a min burst pressure of 6500psi stated
	in the book. We regularly use from 3300 to up to 4000 psi.
	I don't reccomend this,and its hard to get a shop to do this.
	For what we use them for, If they fail hydro, we buy new ones.
	 
	If you can get from 2700 to 3000 psi in them at a shop that should
	let them last a long time. Any more and you should step up to dbls.
