I started off on a rental camber, and then went and bought my own ET. I have to say that I prefer it a lot better. Only gripe I have with it is that I find it a little difficult on harder patches to maintain an edge, but that's just because I'm extremely light for my height.
That's interesting I was looking at the ET myself. What do you use it for mainly? Hear its a good park board, but how does it perform freeriding?
