Which recones to get?

Ok so one of my dd 9500I 15's is blown. I didn't know it was blown till I was finally able to hook it up yesterday after having it for a few months now. Anyways. Should I go with a DD recone or a PSI recone? And I also have a memphis mojo m3 15" with the triple stacked magnet and the orange M basket....I've had it sitting around for about 8 years now. And I was wondering what recone should I get for it also? I already know psi for the mojo, but which one should I go with?
