This is not a question about how the disc throws...but I am curious. At the local PIA Sports, they have some of the new grooves...about 10 and all are the first run star stamps. They are 14.99. I looked through all of them yesterday looking for a lighter weight. I noticed that there was one blue one near the back that felt different. It felt like star plastic rather than champion plastic. Is this possible? The reason I ask is that all others were clearly champion. Translucent and bright and there were a few in blue. The disc in question was also blue but looked and felt much different than the others. The flight plate could be seen through...but only barely, it was rather opaque. And the plastic did not have the slick feel of champion. It felt like star and looked like star but it had the first run stamp. Again, is this possibly a blended plastic? I don't know and that's why I am seeking the advice of the masses. Thanks.
