Ive got a '10 Ride Antic 157 with '09 RX's. The setup is made to go together, and the rx's are extremely easy to adjust. The RX's + Antic are going to let you do anything you want to do and isnt going to break on you any time soon.
Plus 377$ is killer I got mine at like 300~ which was cost. In the end the RX's will be less of a hassle off slopes, and honestly its not that hard to strap in.
