Alright people let's get some things straightened out here.
What Andrew is saying is that doing a Kangaroo flip in the Backcountry is less scary!!!!!! It May be harder to land, but it is alot less scary landing in powder. If you don't make it to your feet, you might still get hurt, but not nearly as bad as if you landed on your head on a groomed landing. Don't get me wrong on this Kangaroo Flip + Powder = Less Scary, Harder to land.
If You do a Kangaroo Flip in the park it's going to be alot scarier to do, but if you land on your feet it's easier to land. However if you don't make it to your feet.......You're pretty much FUCKED!! So Kangaroo Flip + Park Jump = More Scary, Easier to land.
Just take a little time and think. Andrew is not saying that sammy is a pussy by doing it on a pow jump. Just stating the simple fact that it would be easier to try it into pow. And the only way he could try to explain that was by personal experience. Not trying to self promote himself.
Well at least that's what I got from it.
