SurfboardNordica Patron, by far the most underrated pow skis out there...
This is very true. One of the best soft snow skis out there.
the_armidilonew powder skis that are good at skiing in tight trees and freeriding in general.
For tree skiing, there is no better ski than the ON3P Billy Goat or Steeple 112.
Either 179 or 184cm would work for you.
The RES shape, and overall profile of the BG makes for a ski that is increadably stable, yet able to turn and change direction on a dime. You will be amazed at how much more confidence you have when skiing in the trees.
