i always thought a blunt wasn't something that could really be held on a rail as it required having the skis as vertical as possible so it would either be done really fucking fast so you can get across the whole rail with your skis almost straight up or it would be done and then slid down into a normal slide
there's a video of casabon or henrik doing one where they go into a normal slide after in the dew tour or something but i can't find it
