Replying to Line Invaders 09 all mountain/groomers questions?

Hey guys I have a few questions about the 09 line invaders since I have considered buying these and may do so. First off, I like to do both park and all mountain almost equally, but don't have the kind of money to be spending on better all mountain/terrain park balanced skis. I really like the price of these things and most of my friends do park so I am very eager to get my hands on a first pair of twins. I prefer boxes/rails before jumps and I wouldn't be hitting any enormous jumps in the near future. I'm a beginner park skier and i've still been questioning whether these skis are good for me to start on. I'm 5'7'' 115 and live in New England so I won't get to see much powder. Thanks for the help!
