the only thing i can remember jamie thomas doing switch is a 5-0 180 in a line in ride the sky. As far as I'm concerned though when you're that gnarly why would you need to skate switch.
Yeah, he did a swithc 5-0 180 in a line in Misled Youth, also, probably the best I've seen (balanced, and popped out), I want to say at Bricktown with like a front feeble on the rail or something. He also does a switch line, switch crook a bench and then switch boardslide a rail. OH! and switch lipslide the venice hubba!
I can't think of any Markovich tricks ever being switch, but I could imagine some very 90's switch frontside flips in lines going down.
I don't know, it's never really bugged me, I don't even notice when there's a complete absence of switch skating in a part. If anything, it actually pisses me off when kids on youtube leave comments on video parts like "yea he alrite but needz 2 sk8 swich moar" like skateboarding comes with a fuckin' syllabus
Sure is fun to nerd out over, though!
