Replying to Line Sick Day, what's the niche?

Hey all, looking through the Line 2013-14 catalog and wondering what gap in the market the Sick Day was intended to fill.

If I understand right:
The Opus and The Bacon - powder and all mountain freestyle skis respectively
The Influence and the Prophet - big mountain/charging skis
Chronic and Blend - all mountain (with some park)
Most others - park
Sick day - powder? not twin tip? not sure what these are for or why I would choose them over opus or influence if I wanted a wide ski

Thanks for your help guys.
