In very steep, narrow, and heavy Pacific Northwest powder (~20+cm wet snow), I found the turn radius a bit long, and I struggled in tight tree lines. That said, I’m probably not a strong enough powder skier to get the most out of it in those conditions — it seems more geared toward expert powder seekers.
I haven’t tested it on piste yet, but based on others’ reviews, it sounds like it handles groomers and crud surprisingly well for a powder ski.

Very stable even at high speeds, with good float in up to 10cm of powder. Great pop!
I had the edges detuned past contact points, which made the ski super versatile: crud, powder, and moguls were easy to handle. I could smear turns when I wanted and still carve extremely well. An excellent everyday ski with playful character and real versatility.

It can carve almost as well as my Salomon S/Race SL Pro, but I can still press, butter, and pop on the Simply Carver — so much fun for groomer sessions with some park mixed in.
I skied the 160cm (shorter than usual for me), which felt great for carving lower-angle slopes. It did get a little chattery at higher speeds, but that’s expected given the size. If you’re looking for a one-ski quiver for carving, I’d recommend going with your usual ski length.

I tested the Recreation, a more all-mountain focused ski with tons of pop and playfulness. Overall, it’s a great ski for anyone who loves to pop, throw tricks in the sidecountry, and have fun on the slopes and in the park. I tested both the 180cm and the 190cm. The 190cm felt like the right choice—it offers more stability at speed, yet still feels quick thanks to the newschool mount.

I was a bit nervous for this ski because I have ridden directional skis before and honestly disliked them. This ski is of course directional, (designated right and left foot) when I got on the ski I fell in love right away. I tend to be a versatile skier, I’ll ride all over the mountain from park, to groomers, chopped up snow, to big pow faces. The camber allows the ski to have exceptional pop off features and although some people wouldn’t consider a 100mm underfoot ski to be a pow ski, I can assure you that they float beautifully. The tails of the ski feel just slightly softer than the tips but for a playful skier this only works to your benefit. They really are an amazing ski for doing anything and everything on the mountain.

Also able to press nose or tail with ease. It is amazing that simply could create skis like this one. I come from a long snowboarding back ground, and have been looking for skis that gives me the freedom to carve / butter / freestyle like some of my favorite snowboards, and I think I've found the one. The asym cut really makes a difference in utilizing both edges in carving, yet unhooks very naturally and easily for slashes or short turns. For comparison, very similar to the season kins which I've rode for a few seasons, but even better at every aspect of turning as well as freestyle. Don't do rails so can't give any opinions on that.
