As far as weight specific up throw combos, I have all of them memorized, even have in case of platform followups for certain weights. Fast fallers up throw to up smash is always optimal. Samus and Luigi all u can get is up air. Yoshi you can still tank the nair escape with a side b grab after the up throw if they manage it. My favorite combo so far been u throw>sh side b chop > up tilt > regrab up throw> hop side b chop > dair. Shame that above combo requires a platform, you to be under the platform, it raining outside, you to be good at b reversal to follow d.i , and only works on DDD dk bowser and that's about it, maybe yoshi need to check weight chart. Sucks all my followup are weight dependent so I got the chart on my phone to know how to punish till I memorize it. Came from umvc3, maybe if I mained lucario I would have some guaranteed zero to deaths. Feel like I overanalyze this character.
