Someone on the Facebook posted a photo of an Insanity (I believe) that was cracked across the flightplate.
He said it wasn't the first time either.
Friend of mine said he cracked the flightplate on one of those old Medium Proton Eclipse Ions (the really stiff ones).
If you happen to remember where you saw those I'd like to see them too. I'd like to see what the split looks like, how long it is etc. out of curiosity.
To get that stamp to wear almost completely off a disc takes allot of time in my experience, but whatever, the disc looked old. I've tried to break a disc too on purpose and have played disc golf for many many years and have never, ever broke a disc in half. I'd actually be pretty proud if I could accomplish that, even if by chance or happenstance.
I've broken a few discs. Mostly DX Rocs in the winter when I first started playing, which is fairly understandable. The Wizard surprised me because it wasn't a power throw and it was warm out, and I had driven all sorts of Wizards into trees plenty of times.
Have yet to break a premium plastic disc from any company. Even my ex's 100lb doberman couldn't destroy a Neutron Anode we'd play with
