Mentally easy but physically demanding to ski. Mine are mounted at +6.
Bottomless slush is a blast on these. Hellbents come to life as soon as they come in contact with soft snow (slush, tracked out, pow, whatever). They monster truck over everything, and pivot on a dime. They have so much width and rocker than you don't have to think hard about balance and pressure control when turning and landing in soft snow. The surfy feeling in just a few inches of snow is amazing.
They are fairly damp and not too springy. The playfulness comes from being easy to maneuver in places other skis aren't.
The down side is that all that wood makes them heavy. Heavy to hike with, and heavy to spin. They grip hard snow like park skis with detuned edges. You can make them carve on groomers, but it might hurt your knees after a few days. The short effective edge means you have to pivot them further across the fall line than other skis to scrub speed in bumps which gets tiring. I've been using them as a 1-ski quiver for BC trips for 3 years now, and I'm ready to add something more versatile. They are definitely a powder-specific tool.
