Replying to 09' vs. 10' ObSetheds

Was wondering which one you guys prefer because last years is a bit cheaper and they seem very similar in construction. Both have the same measurements 138-105-125, both have a fir core, and both have rocker. The only difference i see is that last years has 15/20 rocker while this years has 10/20 rocker.   (for reference: 15/20 means the rocker lifts up 15mm  and carries down 20 mm of the ski....same for this years except its 10/20)

It seems last years has a bit more rocker and thats it. They also both come in a 189, 179, and a 169

Has anyone skied both and noticed a difference in how they perform in park/pow? Is there a difference in flex?

Thanks. +K
