There was a noticable difference in the CE Aeros and the Champion Aeros in stability, and I believe it to be due to the flimsy nature of the newer Champion Aeros. I don't throw the Champion Aeros because of their lack of stability, and their gumminess. I truly believe you will have a true flying disc with the Coyote if you port it over into a firmer blend of plastic. Thanks Dave for your quick response... I will continue to harass you about proline gremlins though, no offense.
