Wieght Top Tester

this is a test design. I have made a number of toy tops, but I have not actually tested certain characteristics of these tops. I hold a steel one of my own design in my hand, but it's mostly a cut away of a base cone that was 45 degrees, I didnt really think too much into it, it's more of an art peice. reality is, it works well but the wieght is too high. so here is a test design. each of the five tops are slightly different for weight and positions, which will give me an idea of what is better or worse.
