If the highest pressure I could get O2 from the supplier was 2400psi I would certainly have a booster, set to stall out just below 5000psi.

I don’t know if any supplier in the US supplies high pressure oxygen above 2240. I’ve never asked since I’ve never seen it. If we could get 300bar oxygen I wouldn’t have a booster either.
