| There are two "DIR" ways to mount an argon bottle, "cave" and "wreck". Neither gets in the way of your stages.
A wreck mount puts the argon bottle in the LHS waist band, behind the D-ring. It's held snug against the backplate by a bungie. A cave mounted argon bottle is mounted on the left cylinder using straps.
For what it's worth, I use a small 1l argon bottle and wreck mount it, but several of my buddies use cave mount for open water dives.
For both, the stages really are not an issue.
Does this make anything any clearer? Probably not, but it's the best I can do.
