Frigate is a really, really good stage for Falco though. People generally bank too much on the right side of the first transformation in hopes to get a chance to abuse Falco's 'limited' recovery options but they almost always fail [even MK]. I mean, even Olimar has no big problem with it and neither does Falco. Falco also greatly benefits from the platform on the left side and his camping on the 2nd transformation is extremely lame. I really don't like Frigate against Falco.Since it seems like Brinstar, PS2, and RC are gonna be out of the Brawl picture for a while now, I really feel like D3's best CP against Falco is Frigate. On the first part of the stage, if you can manage to throw him off the right side, his recovery options become really limited. It's a little easier for him to laser camp on the second part, thanks to the slopes and that platform in the middle, but I still think it's fairly easy to eventually throw him and proceed from there, although those moving platforms can be annoying... -_-
From my experience PS1 works well because the hazard gives DDD options to move around his laser camping and there aren't too many opportunities for Falco to abuse his powerful close range game. I also like Yoshi's because the uneven ground sometimes messes with his double lasers. Shy Guys can block lasers the ghost can cover our whack recovery options.
