Yeah I only know throw DI intuitively lol. Good correction.
That other question is pretty dependent on % of opponent and stage positioning. Also if it's peach if she's hit by the lasers you can still punish(so the actions before the grab matter too.)
Most of the time you can kind of predict their DI(intuitive but I think most people DI throws out?) and set up position to pseudo combo into FH/DJ Bair if you're a bit more aggressive, or at least threaten with it and then FH Bair or bait them to fall into Utilt. It's like a modified form of Marth juggling but your outranging spacing is very specific(back to them and above you pretty directly) as opposed to Marth's(anywhere above you and preferably also in front....overall space is easier to adjust since his ground movement is better.) You also get rewarded for hitting them more immediately usually(easier setup/kill vs Marth's sometimes laborious juggles), but the setup for the juggle is way more annoying and it's also annoying to position yourself since you're slow. Reminding yourself to move and constantly threaten with Bair/Utilt is extremely strong mentally imo. I sadly only have vs Hbox TO9 where I consistently do this well, but I entirely believe it's possible to do this consistently vs the characters you mentioned(or implied probably.)
If you're by the edge as you implied, then Fthrowing them off is good but ONLY if you work on some good edgeguard setups. I'm honestly not sure if Falco can really gimp those characters reliably but I will also say I've been kind of uninterested in figuring it out. I might go figure it out for Peach though because it could be a great mixup vs Uthrow. I also think there's a % threshold like 15-20% before throw where your Fthrow killing potential becomes viable and before it Dair just doesn't do much. That's more of an intuitive test rule though so take it for what you will.
