Nordica Astral - available in 151
if the info is correct then these are relatively heavy for a touring ski - possibly more a backcountry ski imho.
I would have thought dynafit tour and scott superguides are the type of this you want. these aren't aren't skimo - that kind of race stuff is proper 2 sheets of paper with an edge. there's a decent choice of touring skis around 153: movement apple, atomic backland, dynastar vertical and many more...
at your size and weight I suggest you don't get anything heavy; the proportional weight increase is not worth the minor downhill benefit. you don't want to knacker yourself out dragging heavy stuff around; it's always more difficult to ski in "challenging" conditions - it's the conditions not the skis.
