Hi, this thread is probably useful, the op was wanting to go light, short and narrow:

For a one quiver ski for a range of snow could conditions I think 80 is a bit narrow: 90-105 probably better; which end of that you go for depending if you want it better on hard pack or powder. Though, a more competent and experienced skier can get away with a narrower ski in deeper stuff.
