k2 sight, or volkl ledge, both have sidewall so they'll actually carve. Ledge is symmetrical and flexy, k2 sight is directional and stiff. Take your pick
If your set on line go with the Masterminds, super light, buttery. My brother has them with marker squires, although I'd reccomend you get rossi bindings, never had any major problems, and only 2 minor problems which were flukes.
2009 line invader is my favorite ski ever. probably wont be able to find them anywhere though. I still have mine that ive been riding for 4 season and they're still in great operating condition. probably never gonna let those bad boys go. so playful and you can take those badboys all over the mountain (except in pow obviously)
really depends on the type of skier you are as well as your height, and weight. Check out the k2 press, theyre cheap and a decent park ski with camber under foot and alittle bit of what k2 calls jib rocker. throw some salomon z12 bindings on them and youll be good to go!
