Good question. The side to side has lots to do with balance, ie getting the center of gravity so it sinks horizontally, as well as buoyancy. the foam insert will work, and should help with both. I pour the skeleton interior head out of alumifoam and use an aluminum tube and it works well. Let us know how it works out in ongoing permutations!
