Replying to 5'4" - 105lbs. what ski should i get?

I'm looking to get a pair of fat skis this year. I live in Tahoe so we get a lot of pow. Right now i'm looking at:
pocket rockets (165) - but i broke a pair i was demoing a couple weeks ago so i dunno
motherships (172)
seth pistols (169)
hows the stiffness of the motherships and seth pistols compared to the pocket rocket? the pocket rocket seemed a little too bendy to me. and are the lines as light as everyone says?

thanks!
my level of radness... it just can't... be quantified.
