Mmm ... Most of the places where I ski use mostly "black" for "not groomed", and double blacks are always "natural plus lots of challenges" (expert terrain, not for me). Not to mention that a Green in a place is a Black in another.
In my case, I am working on short turns in groomers and transferring to bumped up/natural terrain. I love a progression from side-slips to pivot turns. My hope is to loosen up my stiff upper body and get some decent separation
But ultimately, the goal is to suck less in natural terrain, in my case. Cheers!
