for JC shines (which are useless :]) i slide Y>B while holding down, for falco u need the find his rhythm since he has a fairly odd jump delay.
for lhdl, when ur hanging on the ledge
flick the control stick down and slide from Y>Bx2.
remember to DI forward (you can do this at any point after the action for the first laser starts) so u dont just go up, shoot and come down and die
i say flick because the control stick needs to be at a neutral position to fire the lasers.
for grabs, falco doesnt really combo as much out of grabs as other chars.
the only grab that has combo ability is a non-teched Dthrow or the more practical Uthrow.
for everything below you need to predict DI, falco has pretty much no auto combos from throws.
-at low %s you can shffl uairs for juggles and some nice damage out of uthrows on most characters.
-also just a regrad depending on DI.
