There is at least one thread out there about how discs of the same mold in different plastic are slightly different diameter because of condensing differently when cooling. If I was better at the interwebs I would link it. Basically the conclusion is that the cheaper a plastic is the larger diameter the disc will be because it condenses less when it cools, and since Star is a mix of Champ and Pro it actually ends up being slightly larger diameter than Champ.
I am, however, willing to admit that the different feeling in my hand could just be all in my head or due to the difference in dominess. But I still like Star best.
The cooling process totally has an effect on the final disc diameter, dome, etc. Different plastics cool faster/slower and so there can be differences in size, etc.
But in the end, the differences are going to be very small.
I think the real difference will be the fact that Champ starts out more stable and breaks in slower while Star beats in somewhat quicker.
