I had the Burton Triads, which were replaced by the Prophecy for 2011.
I bought the 2011 Burton Cartel Re:Flex and slapped it on my 11' NS SL. The bindings are awesome. Super responsive and we all know that Burton has the smoothest ratchets in the game. The Re:Flex discs give you a lot more feel. I'm loving their new gettagrip capstraps. I've tried Union, Rome, and Flux bindings. I would recommend Burton Re:Flex bindings to anyone.
I did the same for my 09 SL-R but have had less than a day on them. So far, so good. And those ratchets are one reason I keep on coming back to Burton bindings.
