i'll bet this has been discussed before, but i can't search the 115 thread pages to find out.
i've noticed some champion discs are clearer... while others are more opaque. i've read before the clearer ones are softer and gummier. are they also less stable than the opaque looking ones?
btw: the discs you've come out with in the last year or so have all been awsome... pro starfire, sidewinder, pro wraith, and the coyote!! i REALLY like the champion gators too, a truly original disc that comes in handy all the time on my short technical home course.
In my experience the clearer ones have been harder and more overstable. At least that is the case with Orcs.
