My best guess out of what's current would be a polished Critical Theory, however the PD was pretty unique. According to a Storm rep, that ball had the most pearl additive of any Storm ball to date. I believe most would agree that the PD is the most skid/flip ball ever produced.
There are some international balls out with the same core as the PD, but they're kind of hard to find.
The Paradigm was a mean piece but as far as skid/flip, the Victory Road is better to me. There were times I could not toss my Paradigm but the Victory Road plays on a wide range of shots. I've joked with my friends that I might punch two more and just carry 3 around and my spare ball.
Bakes...I refuse to bevel my holes!!!
