Have you considered a carto tank? Probably in plastic even if you are dropping things a lot.
The achilles heel in this situation is gonna be being stuck with a 510 connection on your Provari. You are probably too familiar already with snapping the threads off a ProTank base (and others) if you drop your Provari. At least with a carto tank - in plastic - if you drop it you might be out a cheap carto if the carto threads got damaged. The tank itself would survive.
