nolliebackflipI think park skiing is more technical but it takes more balls to ski a sick backcountry line.
They can both be extremeley technical. In the park things might get more tech overall, but that is becasue you can try things over and over. Becasue of this you get crazy tricks that take hundreds of tries, and lots of practice on similair features before hand. For intstance, this wasn't Jesper's first time on s rails or kinked rails, he has spent years practicing on rails similar to this, just not this extreme. https://www.instagram.com/p/B4SXrlLFXmw/?utm_source=ig_web_copy_link
Big mountain is a different kind of technical. Every feature is different every time, and often people are ridding them for the first time. In the park they try to remove as many variables as possible with consitant and close to perfect take offs and landings, and making sure it is groomed so you dont have to even think about the skiing and just the trick you are trying to do. In big mountain, you have to worry about snow quality, obstacles like bumps and trees, weird landings, and the tricks you have to do. Injury is also much more of a risk skiing big mountain, becasue you could be deep in the backcountry or far from help on the resort. If you break your leg in the park, ski patrol will see you and take you down and get you to a hospital. If you break your leg in the backcountry or on a quiet run in the resort with no recpetion, you might just be stuck and have to pray someone will come looking for you. There is so much more to take into account with big mountain, you cant call it less tech because the tricks aren't as hard.
They are so different they aren't really comparable. Obviously the tricks themsleves aren't as technical as tricks in the park and never will be, because it so much more to worry about out of the park. If you can easily do 7's on a 30ft jump in the park, go try a 3 off a 15ft cliff and you will see what I mean.
