Well I was just faced with the exact same question. The answer lies in your circumstance- but the soft from everything I've gathered, isn't soft. I am about 165lbs and I ski in the east except for a trip out west every year. I ski mostly wet, heavy snow here in the east and this will be my pow-specific ski. Seeing as how I'm light in the ass and this will be my powder board, I went soft. If you are going to be using this as an everyday ski, I'd go stiff. If it's going to be your big-dump-only ski, go soft. If you're actually a level 9 and currently rip the thunders a new one, I'd go stiff but you really can't go wrong either way! It's all in what you plan on using it for!
