Replying to Help choosing which of these skis

The discount prices have arrived and I'm in need of a new pair of skis. I will use them for 70% park. The remaining 30% is mostly on groomers, but maybe a little bit on pow. I already have skis for powder, so it's not an issue if my new skis can't handle it.

I'm a thrifty spender and have found these skis, which are all about $200, which should I buy?

'05/'06 Salomon 1080 Thruster
'06/'07 Salomon 1080 Flyer
'07 Fischer Habit
'07 Rossignol Scratch Pro Juniors
'07 K2 Fujatives

Or maybe something else that's about $200?

Also, I'm 5'6" 120 lbs. Would 151 to 161 length skis be right?

Thanx
