(large enough for a second post)...?
My PERSONAL Cps...:
Brinstar (<3), Norfair (if not banned), Lylat (good neutral but usually striked), Delfino, Rainbow Cruise (I'm serious), Pictochat (better than FD imo), PS1.
I know, it's long, but hear me out.
Brinstar, even so coming from a wario main, is decent for pit. You have plenty of planky-goodness. Acid doesnt scare you because you can jump multiple times. You are always decently close to Falco, so he can't run away as much on this stage. You can kill faster just like he can, but your kill moves are easier to hit in this type of range (medium range is best for Falco, but his personal space is violated heavily on this stage). Illusion won't be much of a problem, can be very predictable. Extended hit boxes, albeit favoring the two of you, will favor Pit a lot if you can catch him off guard mid roll or mid-SHDL, or even just recovering (on the side vines). Bair on the vines is delicious if you hit it, and you can scare Falco under the stage because if he illusions above it's practically a free arrow/predicted hit anywhere. You can pressure him more than he can pressure you. His SHDL will be interrupted by his lack of personal space if you just roll with timing.
Norfair is just a personal pick, you can arrow loop easier, they can hit him from under the platforms easier, and it's so big that he's gunna have trouble killing you aside from the occasional screwup you make and get uaired. his kill potential is limited far more than yours.
Lylat is good becaus eof reasons stated earlier.
RC is a given, I don't know if any of you have discussed it, but I wouldn't mind going into what I think makes the stage wonderful for Pit.
Pictochat, if mastered, is a dangerous CP, you can predict a lot of crap here and take advantage. I only suggest it if your opponent is not used to the stage or you know you're in better knowledge of the stage elements as they play a big role in your approach habits.
PS1 is a love or hate type of thing. Falco can excel here as well, but frequent stage changes are good for upsets and throws off his laser game.
Finally, for the starter stage, I always reccomend SV for the pure fact you have dominion of the top platform all the time. BF is okay, but I've had a lot more trouble there than SV.
