nice vid.
i have some questions for you about rob (who i plan to main).
i love rob's playstyle, his huge ranged game (laser/gyro) and his up+B rapage edgeguarding.
however one problem i seem to be having is overcoming his (lack of) speed. almost all his moves have initial lag. thus none of his aerials save his neutral can be used as viable approaches. aside from dash a (which can easily be blcoked/shieldgrabbed) and shorthop-> neutral a, rob doesnt seem to have many approach options.
additionally, the only quick move he can pull off after dodging an attack is the down smash, which usually launches the opponent too high to combo.
also, i saw you use down throw and up throw quite a bit in your videos... why not just use forward/back throw?
