i went threw similar debate.
obsethed has rockered tip and tail, czar only has tip,
and the czar has an almost flat tail.
i went with obsethed and am very happy with my choice
I have the czar and love it, super stable everywhere, I would say the traditional tail maybe its biggest asset, allows of super easy landings, and good carvability, it dosen't smear quite as easily as a rockered tail, but is fun for those who like to rip.
For big mountain i would go with the czar as the lack of tail rocker will make it better for charging. The obsethed is softer and also has tail rocker so it will be better for smearing and switch pow landings.
Abma charges hard on the czar.
I've ridden both and am just giving my opinion from personal experience.
I prefer the the obsethed for my style of skiing, but if i was buying a ski for big mountain/charging i would take a czar.
