i dont know if anyone said this yet but Jason Dill's varial heel in skate more is pretty ill, just the way he lands it and the way his arms are chillin n shit, he just manhandles it.
but the best flatground trick i've ever seen in person, by far, is this Nollie hardflip revert PJ did on flat at the window ledges(r.i.p.) just fucking around one day, he did every other trick you could ever do that day but the nollie hardflip revert sticks out to this day, dude just fuckin rifled that shit off so steezily.
