I do this, the app I use is youtube video flipper. It is awesome and these fucktards giving you shit for it have simply just not tried it and don't know what they're missing out on. Maybe I'm really stupid, but sometimes if a skater is goofy (I'm regular) I will not fully appreciate when they're doing their switch stance stuff. I recently rewatched an Appleyard part from ages ago and only recently realized a tailslide he did was actually switch.
