So I just purchased the 06/07 version of the Armada AR6. The guy at my shop said there was no construction difference between this year's and last year's ski but some sites say stuff like it has a new core. Im not sure if this is just the description of last year's model pasted into this year's so I was wondering if anyone knows if there really is a difference (graphics aside) between this year's and last year's AR6. Thanks
