Replying to How are 07 line invaders? and what size for me?

Sorry if this has been answered, but im new. My local ski shop has the 07 line invader...how is it? Im doing mostly rails and spins right now, no pipe really. And im in vermont, so no insane powder that i need wide skiis for. Also, I want mainly for park, but something that can atleast do alright on all mountain would be nice. Also what length? I really like shorter skiis. Im 5'2-1/2". Ive been using 143cm skis, i know its short for my height, but i like them that way. So anyone know how they are? and if their not great, what is their for me in a low price range? The invaders are going for like $140.
