My time on the Mythic was very enjoyable. It was easy and smooth in the crusty crud and small bumps relative to some of the stiffer skis, but ultra stable, and it totally ripped up the hardpack. Edgehold was phenomenal for an 88mm ski. On the hard snow, it was the Elan 888's equal, if not quite as stable, but it held better than the old 8800. I found it very easy to ski, even in 178 (I would prefer a 172 for my 5 foot 9 frame). Float in the minor crud was great, and this ski had a knack for being relatively easy to ski and very high performance.
It will work well for alot of people. The 888 was slightly more powerful and stable, but with a similiar feel. It wanted to get going a bit faster before coming alive. The Mantra was the other wider ski I tried and not really comparable: superb in the soft stuff, easy and stable, but pretty bad on hardpack. Overall, I would say that the Mythic is a step up from the 8800, and will be great for the solid advanced skier upwards to the full expert. I don't think Dynastar always gets the attention they deserve, but this one is a real winner.
