I've just learnt 270s and switch ups onto boxes but I've having trouble controling the rotation. I'll do a switch 270 on and keep spinning on the box, having to do a bs switch up and then I'll keep spinning on the box. I know for rails I need to scissor my skis to stop it, can I still do this on boxes or is there a different technique? I want to get a bit more control and style into my boxes.
