Zirconium, Mokuti, and Superconductor. See comments for a pic of the other side. This *is not* the base model 😉
With the exotic metals, there’s basically the extra cost of the material, and its 1 sqaure inch per part except for the frame which is 3 square inches. So you can look up the materials to figure out the extra cost.
7, 8, and 10 have yet to be revealed. I may get #7 done today
Ideally the surface between the weight and the frame should be flat so they mate well. Other than that I guess it’s possible. I suppose the mating surfaces could be killed flat, but that would be a lot of custom work.
