It's true that the Cartel back has been softened for this year, so you're not happy with that, then get this year's Mission Restricted. It has the same highback from last year's Cartel with an upgraded ankle strap like this year's Cartel. According to Burton's website the Mission is softer than the Cartel, but definitely felt stiffer when I played with it in the store.
