Replying to Weird situation need help

So i got the 08 pe's as a gift and figured by looking at all the critism that it gets that i should opt for another ski. The dealer offered to trade them for the new k2 extremes for free. So i defenetly think i should do that . Now im wondering if they are park enough for me cause i hear their quite stiff and heavy, so im wondering if i should get the disorderlys instead. I want a ski that can hold anywhere on the mountain but il be riding 75% park so i wanted a ski that is good on rails and jumps.
So in the end its easier 4 me to get the extremes but are they good enough in the park??
