I usually jump forward with j.CD, so I'll try neutral jumping next time I play. Can I still combo EX Press off of a neutral j.CD CH?
You *MIGHT* be able to, but I generally only use EX Press off Counterwire hits myself, I don't like the chance of doing to too early, and eating a combo. I generally use the neutral jump CD wall more as a defense, rather than an offense, you could say.
j.D is so slow! It gets tagged by air-to-air j.As/Bs for free. I only use it to chip away at guard meter during a jump-in blockstring or to start combos if I'm punishing something.
It is slow, but I activate it on the way up. If me and the opponent both jumped, and they're planing to use a move WHEN they get that high, and I used mine befrorehand, they kinda "rest" onto Maxima's hitbox, and get hit, before their high-aimed Air-to-Air normal makes it out.
Risky, again, but it works in odd ways on occassion. I prefer staying grounded though, but I use the kick when jumping over fireballs sometimes, as the more-downward-than-bodybox attack does a good job of trading with DPs and stopping run-after techniques. This is during those annoying time when Lag / personal timing is making me sloppy-hop over (and thus, into) projectiles...
I remember specifically seeing a japanese Maxima use cr.C to LOW GP Andy's cr.D (sweep) and cancel into Weak Vapor Cannon. You're saying non of his moves have low GP?
This is where Maxima's GPs confuse me, you see, which Is why I wish for more GP documentation, haha. For me, it always seems like his GP box is more of a "If GP box meets attack box, GP works" style thing, which means that a Higher-up sweep can sometimes be guarded by a GP (Like Terry's or Iori's), but true "on the ground" lows will always win out (Such as most cround B's, and Maxima's own sweep.)

In the bit of online play I did just recently, I have to say, his DM (and EX) is even more effective than I've traditionally given it credit for. I tried testing the Invincibility of EX DM VS sweeps in training, but only had a few minutes to do so, and came up with no conclusive answers... so if anyone wants to try it out VS various sweeps and such, feel free to do so!
