Really depends on the local Id say. I cant imagine there is much of an issue catching a branch in pow if you are above the treeline out west, however if you drop the pole into bottomless pow during a wreck, your probably never finding it again.
Granted I am an east coast skier, so what do I know? Even in the glades out here, I try very very hard to not come so close to trees that that would ever be a problem.
