ah the days of super raleys! Yeh if you time your scoop right before the carrier clicks you can go massive, everyone pretty much stopped doing since its pretty dangerous. You can still get some of the effect by taking a wide cut around the corner and edging super hard but short right after the click, thats pretty fun.
If youre after a good tutorial my mate made this a while ago, pretty good
