I mean they are literally made from existing mold pieces Discraft HAD. Not like...oh this mold is based off a Roc.
I've heard:
Zeus - Kong proto driver that never made production
Anax - some version of a Tsunami
Malta - Nebula
Luna - modified Roach
Sure, but that´s a nice way to do it. . "i like this disc but i want it more OS---sharper edge..more rounded edge and so on"
So if i hade to guess PP new putter will be something like a less deep and less stable Challenger SS
