I have two custom made solid lead keel weights. These fit in between your doubles behind your backplate. They are drilled to fit 11" spacing, there is some play available.
The smaller 4.5lb weight can also be used on the inside (between you and your backplate) when backmounting a single tank. I used is that way with an 8lb steel backplate and an AL 80 in Bonaire a couple of times.

The larger weight is a modular 12lb weight. I cast it around some stainless steel bolts and threaded rod in three 4lb sections. You can use 1,2, or all three sections depending on your exposure protection and buoyancy needs. If you only use two sections they can be unscrewed several inches to provide some trim adjustment if necessary.
