Outdated? Thats an interesting claim.... could you explain what you mean a little more?
I hated the JJ's- they are IMO a far worse design than the Obsethed for big mountain skiing- charging and dropping cliffs, although the Obsetheds are too soft, especially in the tails, for my tastes (I'm 5'11 150 lbs). I liked how damp they were. The JJ's on the other hand have a stupidly short turn radius and a very strange flex pattern that make them unstable in crud or at speed, especially on edge. On the other hand JJ's feel better in the air, have a better swing weight, and are better at landing switch in the powder. I haven't skied the Blogs so I can't comment on them.
