Replying to Nordica Zero

First of all, I searchbarred before making this. There have been a few threads about these skis, but none of them have any quality information. Please help me out if you actually have skied them or have a real knowledge of them. Not trying to be a dick, I'm just not looking for people saying yeah they're sick you should get them. I'm thinking about getting a pair for the upcoming season. I'm 5'11" and 155 pounds and I ski aggressively. I'll be using them for all-mountain. They're a symmetrical twin and I like skiing long skis, so I'm thinking about going with the 184 cm, but I'm not sure if the 178 cm would be a better fit. I've demoed a lot of 08/09 skis, but Nordica wasn't sending many Zeros around to demos, so I didn't get a chance to ski them. I'm just looking for reviews of how they ski and which length makes more sense for me. Again, please help me out if you've either skied them or know a lot about them.

Thanks in advance for the help. +Karma
