I mounted my Edollos at -1 and love them there. They're a very versatile park ski and feel amazing on jumps because the tails aren't rockered, and the medium flex is stable without being too stiff to play around. Landing on them feels very smooth. Took a while to get used to the weight + width on rails but no problems there after a few days. They're decent all-mountain too but I have other skis for that.
Unlike the other poster's mine lasted a long time. They have about 80 days on them and only one blown sidewall, no missing edge. I ski rails pretty hard and they've put up with lots of shit. They're still ridable even though I replaced them with some ARV 96s (edollos are better btw)
