I have skied this ski. It's not as true "Big-Mountain" has some here would have you believe. I found that at high speeds it felt a bit loose when compared to, say, the Head Super Mojo or Seth's K2 offering.
It's true that these are not the skis you'd ski in bounds much. They work, and you can carve groomers on them, but the dimensions are much better for mixed snow conditions (crud, powder, broken up junk) than groomers.
I really liked the Ant on steep, mixed terrain with soft snow. Trees, pow and cliffs. It's quite quick in this type of terrain with a surfy feel and the ability to get sideways fast when you want to dump speed.
Of course, this is merely a reflection of my experiences on the Ant, yours may be different. For the record, I clock in at 180lbs, am a very solid skier with some international competition experience. I tend to spend most of my time in the backcounty these days and prefer cliffs, BC booters and powder to the park and pipe scene. If you're like me, you may like these skis. I thought they were really fun. And of course, the graphics rock.
