Replying to Which powder ski?

Hey, I'm trying to figure out what ski to buy for big-mountain/pow/occasional park and was hoping you guys could help.

My home mountain's basically a huge park in southern california but I already have a pair of 175 arv's for riding there and I'm going to be visiting a lot of different mountains (Mammoth, Whistler, Tahoe, CO) for the next few years that I want some more burly skis for. Choices are...

08 Line Sir Francis Bacons (too soft for charging? they look like they'd be a lot of fun in the trees)

08 K2 Seth's (will these be awkward in park or on-piste cause of the rocker? too stiff for screwing around on-piste)

08 Surface Live Life's (these look like the best choice so far, midway between the bacons and seth, stiff enough for charging but not too stiff?)
08

Thanks for any input.
