I just finished my first loooong day out on these: 14 hours and 7000+ feet of everything the late-season east Cascades has to offer. Ski carry in, boot packing and skinning through brushy undergrowth on rotten snow low down, big fields of perfect spring snow, skinning up steep crusty awful, occasional pow stashes. Normally I would have preferred something skinnier for this kind of day, but the Hang5 was all I had in the quiver so I gave it a try.
I was very pleasantly surprised. These aren't the very lightest (don't forget the weight of the mondo-sized skin you need to cover those bases), but for their width they're excellent. The camber and sidecut under foot made them bite really well on firm side-hill skin tracks, and the width kept them on top of crumbly rotten stuff on the up. On the down, they absolutely rocked: floaty as you'd expect on pow, but with firm, poppy tails that made them amazingly snappy and fun on firmer spring snow. These definitely have personality; the slight bulge in the tip rocker can really bring them around quick when you engage an edge, and they reward aggressive weight-forward charging with none of the vagueness that super-rockered pow skis can yield when initiating turns. The long effective edge also gives them great bite on firmer snow, which was nice on the long, route-finding, cliff-band-dodging ski-bushwhack nightmare that was our exit route. I haven't yet taken them out in deep powder; I expect they'll float great due to the fat, rockered tip and handle well at speed, but perhaps lack some of the surfy-smeary playful feel of a ski with a more aggressively rockered tip and tail.
All in all, I'm really stoked about these skis. They are pretty sweet in nearly any condition, and definitely inspire confidence. If you want the float of a fatter ski but the stability of a flatter tail and the ability to crush any condition a long backcountry tour can throw at you, these rock.
