Yeah, IIRC, the PDGA made them quit making them as they exceeded 27 lbs on the taco test.
But what is in a name?
Tis but thy name that is my enemy;--
Thou art thyself, though not called Wizard.
What's Wizard? It is nor flex, nor flight,
Nor core, nor plate, nor any other part
Belonging to a disc. O, be some other name!
What's in a name? that which we call a plastic
By any other name would feel as sweet;
So Medium would, were he not Medium call'd,
Retain that dear perfection which he owes
Without that title:--Medium, doff thy name;
And for that name, which is no part of thee,
Take all myself.
But seriously, start with the OP in this thread. At this point, it's personal.
