That's it. Compare the bottom of the rim flashing location on your prodigy stuff to other manufacturers discs (except Latitutde, which I think does what prodigy does). Rather than the flashing being at the exact point on the bottom of the rim where the inside rim meets the bottom of the wing, the flashing is moved a little further out on the wing. It means that you don't really feel the flashing when you throw, even if there's a significant amount.
