I've watched Rolo's video several times and I think it pretty much confirms what I've been saying in previous posts.
I'll quote myself in case the point was missed:
The turns are not tight enough, a true fall line can't be maintained in steeper terrain with the "hop" cheat down to the next mogul face, you'll take a pounding and blow up. Gotta link the backside turn.
The L4 demonstrates this @ 2:40 and 2:50. The turns aren't tight enough or quick enough, he can't retract in time to get the shovels back on the snow and engaged and more or less jumps down to the next mogul face landing on it with both feet, to slow. Not a successful tactic in steeper and firmer conditions. In those conditions he should easily be able to get the shovels down, engaged and "turn" into the next mogul face.
They all seem to patch it together at some point because the turn isn't tight or quick enough.
It's just when the pitch goes to 30+ degrees, they are going to either have to drop back into the ruts for speed control or blow up without focusing on linking the backside turn. If you know of video that shows me wrong, post it. From everything I've seen, if they turn into the mogul face, it "pops" them and they usually air over the backside down to the mogul below like I described above.
I'm very critical of the hands and pole plant though, not for aesthetics but for technical reasons.
Watch Rollo's section starting at 3:04, the pitch looks like a steep face and the moguls look firmer, but edgeable. This is where the 2 footed even pressure turn falls apart IMO. To slow and not tight enough.
My intention here is not to "beat down" Rollo, I applaud him for posting the video's (everyone should IMO), as I don't see much difference across the L4 spectrum of vids posted, it's not the skiers, it's the turn which limits the tactics and execution.
While Rollo gets down the face, there is nothing fluid or playful about it IMO, he gets himself pretty much confined to the established ruts (very low in them) to maintain speed control and continuity. In this clip, I'm thinking Rollo didn't have the luxury the skiers in other L4 vids had where they could basically reach mach speed as they shot out of the section into a relatively flat and smooth transition at the bottom, speed control be damned.
The turns in this section don't have the defined and powerful finish needed to establish an independent cadence , he's way to low, deeply bent knees, to extend into the turn finish and usually by the time he stands tall (late) he's already past the point of retraction and transition where the tips should be down and engaged. He often pops the air turn and steers/ twists the skis downhill with no edge contact to make up for the missed moment.
Lot's of upper body twisting and pulling to make it happen with a few hanging turns as he waits for the next terrain change (bump) to bounce him into the next air turn and direction change. Very little shovel edge contact in transition and the high "C".
You can't turn into the mogul face and link the backside turn without establishing early (instant actually) shovel edge contact in the steeps. Due to being late for a myriad of reasons, shoulders twisted to the fall line, out of balance aft, poor hand position, a skier gets forced to trace the ruts of the 100's before them quite quickly.
The hands and pole plant are so important in natural terrain. Rollo's pole plant is really hindering him IMO. Throughout all of the clips, he often drops his left hand below his waste and in a few left turns, almost drags it as if skiing on the groomed. There's simply no time in that type of terrain to make up for that weakness, it causes him all kinds of problems IMO and if it isn't already, should be a major focus in natural terrain.
