I did some lazy recording with a thrown-together layout and ended up getting a MM recorded against my brother's Sheik, as well as a few silly friendlies vs. his extra-fraudulent falcon secondary (and a wonky, 2006 DI movestring on it start of the 2nd friendly that I dropped the 0-to-death on >_>). My Ness is still pretty bad, and we both were quite sloppy this set, especially game 1, but might as well share ^^''

Have you guys experimented at all with fair into YYG at all vs Sheik or any other sorta-floaty character for mid percents? I don't think there are any percents where it's a proper combo, but it seems like a pretty easy setup if they miss a CC on fair and don't already know to buffer a roll out afterward or something.
