As a minimum, put button type spgs on deco bottles and real spgs on stage bottles. Any bottle being dropped must be checked at the point of dropping. If it is not what you expect, the dive is over. Even if you are carrying the bottle with you the whole dive, the peace of mind is worth it. If you try it both ways, you will agree. Come on guys, this is tech diving 101.
