Replying to Help me pick me first pair of skis!

Ok so, like the title says, im just getting to hardcore park skiing this year (its not rly my first pair, i can ski), and im super super new to all of this junk. ive been snooping around for a while trying to make sense of it all, with a little success. Ive been looking at what different companies have to offer too, and these seem to be what im looking for (as far as i can tell anyways)
invaders/anthems
silencers/fujatives
1080 thrusters

these are all keeping in mind that a have a pretty limited budget. im assuming of course that i can just use my existing bindings and boots(can i?). what are these choices like, and are there any others i should be considering, which im sure there are?

yea, for other info, im 6'1", 165lbs, and im on the east coast (that seems to be important-im not gonna lie, i dont know why)
thanks alot guys
