Replying to What do you think?

I'm looking into new skis..First of all i live in ohio and ski primarily in the New York/ PA area. soo mostly hard pack and ice and crust. I am 5'10 or so and only like 150lbs so im lookin at something around 170 for length. Also..I'd say i spend around 50-60% of my time in the park and the rest of the time all over the "mountain". Heres what i'm lookin at so far. any suggestions are welcome.

06 chronics 172cm 110-80-103

06 pe's 174cm 118/85/109

06 scratch fs 174cm 116-84-109

thanks
