You're of a size and weight where you could very easily handle HP steel 117's/120's/133's...
Further there are heavier S/S back-plates available...
You seriously need to upgrade your 3AL 80...or get used to diving with all the additional ballast...
If you're going to jump into the water with ballast...it may as well be something you can breathe from...
Finally...I don't suggest doubling up 3AL 80's...in you case...it may help you slightly as long as the cylinders are full but compound your positive buoyancy problem once they start to empty...
There was a guy in Central Ontario...Gary Hoadley...who made a 10 pound s/s back-plate...G.U.T.S. Gear...I tried his last known e-mail...it's no longer active...
