I mean 159 is too short for him. But all of you guys telling him to go long?? What if he's a beginner and sucks. Long skis will just frustrate him. And perhaps turn him off of skiing. You don't need long skis because it's the cool thing to do, or it "looks better". You need to be able to effectively ski you skis. And if they're out of your ability range, you won't be having a great time. If you're a beginner, you could go with something like 170 cm. His weight is also a factor too.
