Why those two may I ask? They are very different skis. The Ova is a fairly narrow, soft-tipped resort ski and the Supernatural is a relatively stiff charger.
Looking for something a bit more advanced than my current ability, and both seemed quite suitable, with the Ova seemingly a bit more on piste oriented.
Although i guess I don't quite know enough about the differences
I'd narrowed it down to Supernatural 100s and Black Crow Ovas,
altho I just spotted this price.. so that may be a swinger - http://shop.epictv.com/en/ski-100-109mm/line/supernatural-100-2016?sku=LIN16SUP100172
