I think the Da Nollies are a better choice. Symmetrical, light, durable (I have 60+ days on mine a only one miniscule edge crack), amazingly poppy, once they break in the butter zones make it so easy to butter, if it means anything to you the graphics on the 2010 are 1000x better than the Anthems (in my opinion), and lastly your supporting a core company located in the United States that has some pretty badass people working for them. Only downfall is that they lack with all-mountain performance
I have no experience with Anthems so I cannot say anything about them, but if these two skis where laid out in front of me I would probably go with the Da Nollie.
