The Heroine should be just fine for you. It is a bit towards the soft side so at your weight it should be super playful and easy to turn. I am guessing you were leaning to that because it comes 158cm, but if you were going to go longer to grow into it the Wednesday is the exact same ski with a slightly stiffer flex pattern and starts at the 168cm. Even though it is stiff the Wednesday is not that stiff and is still a very fun and snappy ski.
