In reply to featuresforfeet:
On paper not exactly what you want but I run a 99 DPS Wailer with tech bindings and think it is the dogs bananas.
It's not heavy and skis like a much fatter ski but has pretty decent manoeuvrability, I've skied fast open deep powder in it and steep narrow couloirs and loved in in both. It will also perform better in crust/crud and mixed conditions than other skis.
Not sure how the weight actually compares, sorry, but practically I've had no problems and find going up a joy.
