As Snowwolf says, there's no reason not to make controlled turns when it gets steep and narrow(45deg/3m in this case). But it's definitely easier on perfect snow.

Not sure what it looks like below that chute, but if it's a big wide open slope I'd probably just Xavier De La Rue that chute and then lay down a big, sweeping, powder slinging turn across the slope.
