There is a lot of confusion around this board. I have a Nug, a stairmaster extreme 156, and a 155 joystick. my 146 nug is more stable than each one of those boards. it is not a soft board at all either. It is a go everywhere board. I could post a video review to show it off sometime this week if there is interest. I highly recommend.
There is more to the nug than just shortening the tips and lengthening the edge. the core has a lot going on to add to the stability.
