well i just rode my whole season on them. A++++++ in my opinion. they were my 1st pair of twins and i really liked em. after 46 days of riding a ton of rails the edges are fine. just worn down under the boot but no cracks or nuthin. as far as outside of the park they were fine (although my mountain is only 400 ft.). the only drawback i foud is that they're bad on ice. for the price (i got them w/ bindings last march for only $320) they're great.
I ride a pair. They are by far the most fun ski I have ever been on. Mine have yet to become reverse camber but I have heard some peoples have. All and all such a fun ski for playing around on, quility is what you expect from such a cheap ski.
They are not good if you are heavy like me outside of the park and arn't particularly well made. But they are CHEAP!
Sport Conrad in Germany is selling them for 150 euros (like 170 bucks?) with shipping on top.
