Which tank do you think is better to use for Nitrox, steel or aluminum? Or does it make any difference? Thoughts?
 
Tank material should be based on your diving habits. I don't think it matters either way for you as the diver. The difference comes in O2 cleaning the tanks. Steel is more involved, and thus, could be more expensive to get O2 cleaned than AL.
 
Doesn't matter for EAN. Steel's advantages are size & bouyancy characteristics. Aluminum's sole advantage to a diver is cost.
 
aluminium are easier to o2 clean - no flash rust - so I prefer alu.
