Thanks very much for your answer :)
I've started skiing when i was like 3 but then when i turned 12 i decided i wanted to snowboard and now after 6 years i really wanna ski again, because it's just so much fun. So yeah it would be really nice if you could help me a bit. I'm 1m79 ( 5ft9-10in) and weight 140 pounds. I'd like to stard doing some jibbing nd jumps, but also skiing on a normal slope. I'd really like to take the chronic, but i'm gonna have a look at the skis you told me. what size shall i take it?? 173 or 78??
