Replying to What skis and what size is best for me????

im 5'10" and 140 pounds and i just started to get into skiing last year and i bought a pair of skis over the summer at a local shops tent sale. they were 169 scratches, the white and red ones, and i really need better skis this year bc im going to colorado for a week and i want decent skis that can handle powder and stuff. currently i do about 40% park and 60% piste but its usually ice bc my mountain sucks. i think i need bigger skis asweel so i would like to know what the best choice of skis/bindings would be for someone like me, and i have a $600 price limit which i think i can get something decent with. i want something that can handle smaller jumps (40ft max) and ice along with powder and some bumps. whats a good ski for me?
