To each his own. Just remember that overfilling tanks stress the burst discs, so they should be inspected from time to time. I doubt that the hydro guys even bother to look at hydro time.
Also, consider the forces that the threads have to contend with when overfilling. I’d make sure the VIPs are done at a reliable inspection station, rather than some newbie instructor at a dive shop where staff come and go a lot.
Consider that an 80 cuft tank @ 3000psi has about 1,000,000 lb of potential energy stored, and it’s on you back or under your arms...
But, regardless of your choices, dive safe! Cheers!
