Warning: High Risk ; Higher Reward.
Pick up on your opponents habits and maybe get a flashy kill
Recoveries that opponents like to attack out of and bypass the ledge grab. Ex: Sonic likes to UpB into fair
Sonic UpB, Mega Man UpB, Bowser Jr. UpB / Side B, Wario Side B
Recoveries that have specific animations before grabbing the ledge. Ex: Ike's aether
Ike UpB, Cloud UpB, Shulk UpB, Kirby UpB, Little Mac UpB / Side B
Recoveries that normally dont grab the ledge at all (or have a very small sweetspot)
Villager Side B, Luigi Side B / Down B, Dr Mario Down B, Wario Down B, Peach Side B, Bayo Up B
Recoveries that behave differently when they come in contact with a hurtbox
Dark/Pit Side B, Captain Falcon Side B, Ike Side B, Sheik Down B, ZSS down B,
Recoveries that opponents like to use to climb onto the stage
Fox/Falco side B, DK up B, Ryu Side B , MK neutral B, Bayo Side B
Recoveries that opponents to like to go high and onto the stage with
Mewtwo UpB, Zelda Up B, King Dedede Up B, High Aura Lucario UpB, Sonic Up B
Also any recovery that doesnt sweetspot when poorly spaced, which is like a lot of them but most commonly I see Ryu UpB, Pac Man UpB, Ganon/Falcon Side B, Fox/Falco UpB.
Very effective on Ike's Up B, pulled this off twice on my opponent forcing him to try and space out his up B lower- which isn't always possible depending on his horizontal distance to the ledge.
Full Charge SL also has super armor throughout the length of its hitbox.
