I am planning to buy a new set of skies and I am choosing between Influence 105 and Prophet 98. I am mostly skiing in Scandinavia and the Alps. Aprox 50% of my skiing is outside the slope, in the forrest or on hillsides. I am 179cm height and my weight is aprox 77kg. I am intermediate skier but I want to be better. I also would like to ski more outside the slope then I do today. Which of these skis and which height do you recommend?
