In a dry Texas attic I don't think the busted burst disc is a big issue, or you can send it to me to keep my 6 72's company.

I would say make a mail box out of it or give it away , cause a 72 as you guessed has less air in it than an 80 so the dive buudy of yours if hes got a 72 wondeful if he has an 80 hes going to pissed at you calling the dive cause your always short on air, also the bc strap will always have to be changed from the 72 from an 80....and the cost will be the same as an 80 fill, so now you have 3 negatives on keeping the 72......enjoy
Steel 72's are 72 cubic feet within the first 5 years of existence. The tank is rated with the 10 percent overfill, but since it is so cost innefective to get the plus stamping on tanks that most people wont spend the money. Steel 72's after their first hydro are actually about 64 cubic feet. So there is a big difference between that tank and an AL 80. This doesnt mean that the tank is bad though, i will occasionally use a steel 72 on a shallow quarry dive or a niagara river drift dive. Just realize that these tanks are really not good for deep dives. I would not reccomend putting a different burst disc other than the one that is rated for the tank, overfilling tanks is bad for the tank and can also be bad for the person filling the tank.
