I found a Cyclone in the woods at a park today, and there is "Property of Isabella County PKS" inprinted onto the bottom of the disc. I literally mean that the letters are indented in the plastic (picture attached).
I plan on returning the disc, there was just no one at the office at this time, but would this disc be legal to throw at a tournament? There is rule 805 B(6) which states a disc must be "be essentially as produced, without any post-production modifications which affect the weight or flight characteristics;"
It is a modification, but I do not think it would affect the flight in any way (or at least any more then the words Discraft has printed on the disc). What is the ruling, is this disc legal to throw at a tournament?
