The late flip stuff is very P-Rod and maybe 1 or two others. I agree that prob shouldn't be a thing either. It's especially annoying when he just combos late flips into a bunch of different tricks too.
backside makes sense, sort of I swear i saw sewa do one with the sneaky-frontside-revert, which just seems to defeat the purpose of a hard flip. almost like theres an invisible ledge/rail? doesnt sit right with me "do a grind in the middle"
I did have a skateboard from like 1981-83. I can't even remember the brand, but it had brown and orange wheels. I think it was about $40 at Alternative Bike and Skate. I never really got into all that skateboard stuff, tricks, ramps whatever. I found it boring and injurious.
