I picked up a new PD today, but it's raining, my son has basketball tonight, and I might not get to throw. Compared to the G-line PD I have, the new one is nearly identical in wing shape, shoulder, micro-bead under wing, feel. The new one has slight more dome and perhaps a touch deeper, but the plastics are very different, and the old one is beat up. Any differences look as insignificant as variations within a single run.
I looked at a few dozen in the store and there were varying degrees of dome, and I grabbed the flattest 175g red they had. There were flatter, even board flat in the 170-172g range in highlighter yellow. But I wanted red.
In a few days I'll also have one of the new prototypes to compare.
Had Discmania released the FD3 instead, I probably wouldn't ever have looked at the PD. The G-line I bought used because I have a hard time finding a faded pink FD3. I am hoping the new PD is more stable than the g-line, and a slides in to replace the FD3.
