I have never thrown one, but was thinking about it. From what I have read, it is a Stingray with a bead (slightly more stable/overstable). What plastic do you throw in this mold? Champion plastic Cobra is supposed to be that much more Overstable (Champion plastic).
I have a Cobra but I've never been able to do much with it. However, it's one of my golfing buddy's "go to" disc and he has about 5 of them. I've really come to hate seeing them come out of his bag because he's won quite a bit of money from me by hitting an uncanny number of ridiculous shots with the things. I jumped for joy when he threw his favorite one in the pond at Newton.
