Replying to Twin-tip All-mountain ski

Hey everyone,

My name is Anna and I ski in the Alps in Europe and in Australia. I am currently in between a level 5 and 6 skier, wanting to take quite a few lessons this winter in Europe to improve. I am looking for an All Mountain Ski, I can ski well on piste but also be able to make myself familiar with off piste/powder skiing. I would say my main priority is to learn to ski well on piste. I really would like to get a pair of twin tips, as I would love to learn how to ski switch. My partner has always skied twin-tips and absolutely loves it, we got a bit worried though that I might find to ski a twin-tip ski a lot more difficult. The ski I liked the most so far is the Line Soulmate 90 and I am trying to decide between a 158cm or 165 cm ski. I am 167 cm tall and weigh 57 kg.

I would really appreciate your opinion.

Cheers!
