Cool thanks.I believe the FS Hero bottles have no death date, so can potentially outlast their owner.
most everything runs on lower pressures these days, so you should also be able to set your reg to around 450 and be good to go!
Interesting.... which is the other bottle?Technically any bottle with the new UNISO 11119-2 certification has no death date as long as it passes the hydro test every 5 five years, but first strike seem to be the only ones openly advertising this fact, i guess the other manufacturers are still putting a death date on their UNISO 11119-2 certified bottles because they want to carry on selling new bottles, though i have seen at least one other that has no final date on the bottle..
