Looking at the TenPoint 2020 lineup and the Wicked Ridge RDX 400. The RDX 400 is cataloged as new for 2020. I purchased a 2019 RDX 400 back in April of this year and is cataloged as new for 2019. What other changes were made in the RDX 400 to make it a new for 2020 product other than the switch to using Alpha instead of Omni nocks?
