100% agree with Dave and John here. Your housing will not break down because you don't soak it overnight for a 6 days diving trip (let alone a 14 days diving one if you're doing it).

Just rinse it, take a shower with it if you want to make sure, and then dry it properly by bringing it in your cabin.

I've seen more floods of cameras/gopros that were left in rinse tanks than from being underwater! :)

I have both the Cinebags grouper and the AO cooler. I like them both but for different reasons. The AO cooler is much thicker and provides superior padding when traveling around with my rig in the cooler. It also is much taller so you can get a housing with a monitor on the top to just tuck in. My zipper is still alive after a couple years. It does not travel super flat so harder to get to wherever one is going diving. However, when closed up with the flaps down it is a nice padding setup!

The Cinebags - (now Kraken... somepoint would like to know how that happened)- is great for strobe + mirrorless housing and arms but no monitor. Plus it fits nicely in a XL Duffel bag (in particular a North Face one w/o wheels) so I use it as a packing divider for all of my camera stuff when flying/traveling to the dive site. It provides nice extra protection for float arms...all that kinda stuff for baggage handlers. When I get to my destination it then becomes my camera moving device on and around the boat but I am always right at the size limit for it with 180mm dome and a couple strobes.

I don't do enough live aboard diving to have an opinion on using either as a rinse tank. I have definitely used both as rinse tanks on the dock at the end of a day of boat or shore diving to make sure they get a good wrinse.
