I laughed at the 90% thing also...
I'm riding 177's loaded with Z12's and the combination is ridiculous. At 200lbs I'm very happy with the stability and swing weight of the skis. You can rip zipper lines in tight moguls, float knee deep powder, charge groomers and rule the park.
My only advice regards ski length. There is much debate between 177 and 185's for those in the 175-210lb range. I haven't skied both, but don't hesitate for the shorter of the two. This is a beefy ski and you can get away with the shorter size.
Oh yeah, one more thing, the top sheet on the 07's is suspect. I've only been on them 5 times and they aren't holding up even as well as my 1080's...What? Yes it's true, and I've only done a couple rails...
