In reply to Mr-Cowdrey: I think you are thinking too much about something you realisitically won't be doing any time soon, i.e. proper (scottish III and above) climbing with skis on your back, as you wont be good enough at skiing to get down anything that would neccessitate.
It would be much better to get some skis that are longer and better for the skiing, than worrying about how they would affect your climbing, and concentrating on getting better at skiing before you think about skiing into climbs.
Also I don't think a weeks piste skiing in austria would give you the skills or ability you need to go off piste with a heavy pack skiing into climbs or touring, especially on 160cm skis.
Don't underestimate the difference between resort skiing (even 'off-piste' in resort) and properly non touched terrain, which can have ice, nice snow, awful avalanche debris, a thin track, some breakable crust and some re-frozen stuff, all in the same run.
