Everybody knows these skis are badass. If you are looking for a pow ski that will rip through crud and charge as hard as you can push it while still staying playful and agile, I recommend the Night Train for sure.
At speed these guys feel like two freight trains, you can transition from crud to untouched back and forth without having to worry about your skis noodling out. The Night Trains stomp big airs effortlessly, and have a relatively low swing weight for future spins.
These guys are nimble when you want them to be, and have enough float to keep your tips from diving on those reeally deep days.
In short, I would probably put the Night Trains as the best pow ski I have gotten the chance to ride.
