I have been using Tribolube 71 for all my o-rings for yrs too. It works perfectly and does not react to the different o-ring materials, no swelling.
I got tired of carrying a different grease for Subal black o-rings, Inon yellow o-rings, Sea&Sea blue o-rings, Olympus red o-rings.
Another option is to change all your o-rings to butyl (black), use no grease and just use saliva as a lubricant as one of my dive buddies does.
