The One is Whitedot's only park ski, the rest are all freeride skis. From what I understand their freeride/pow skis were fairly well received by quite a few different people, reviewers, ex pros etc. (I heard Nobis rides one of their models). Whilst one of the founders is British (I think) they run their company and build their skis in Chamonix. Saw their booth at the London Ski Show two years ago, they seemed like a legit company.
That's about all I know, Joey
