Because one of my thick (red) shims that I had in my Hitman broke (due to an unfortunate accident that needs not to be explained). I had a pair of thin (grey) ones lying around, and, setting them stacked up on a table next to a thick one, they appear to be the same thickness. Am I correct in this assumption? Also, is using one thick shim on one side and two thin ones on the other going to make my yoyo unstable of unbalanced?

As a side note, how would playing with one thick and one thin shim work?

Yes, the thin/gray are .015" and the thick/red are .030".
