Replying to Armada Magic J OR K2 Pettitor

Alright, so I'm looking for a pow ski and have narrowed it down to the Armada Magic J and the K2 Pettitor. I currently ride K2 Kung Fujas and love them, but they're super weak. You can scratch the base with your fingernail and the top sheet and sidewall scratches and dents super easily. But they ski amazingly so I am open to getting K2 skis again. I do like how light weight Armada skis are, but have never ridden them and have heard mixed reviews. It seems like everybody likes the Pettitor and the few reviews I have seen on the Magic J have been good too. This would be my powder specific ski for mostly inbounds skiing and sometimes backcountry. I ski Alaska, am 6'4'' and 155 pounds and am looking at the 189 Pettitor and the 190 Magic J. Which ski is more fun, which has better durability, and which floats better. Keep in mind I will be skiing thick, heavy Alaskan powder, so it needs to float good. Thanks in advance.
