I jsut made it on the InfiniteDiscs reviewer team and got an Underworld and a Tursas (already ordered two Stags as well as an MVP Tangent) so I'm pretty psyched to see how they fly. Opto Yellow for the Tursas, Light Blue Tourney for the Underworld. Tursas is 169, Underworld is 168. I am VERY excited to see how these fly...and I should be getting them soon!
As for the probnlem of them not launching many, I would reckon that they have much more stock for the European release (including their baseline plastic) While America is a huge market, I think Westside's biggest market is in Europe. Plus it costs more to ship to America, all that jazz.
