They looked similar to the angled HM5 pads I've seen floating around online, and I know LFF uses the regular HM5 (FA-003) pads on the Paradox. Or, at least, he did. Not sure if that changed.
I'm not trying to suggest the Code-X pads aren't handmade, BTW. That's just what I would have guessed he was using based on those couple pictures I've seen had I not been told otherwise.
