Nidecker Carbons. I use an old version of these on my very stiff Palmer Centric. Nidecker Snowboards - Carbon Black/Orange
I've used them on everything from icy midwest groomers to Chamonix off piste. Stiff bindings are great but overkill if you ride a more flexy board.
I've ridden two pairs of Nidecker bindings... one was the 800, and the the other was 900 Carbons(?) back around 2005-2007 era. These were very good bindings with an extra thick eva foam pad under the binding (so much so that they came with longer mountining screws). Stiff, responsive and damp. I would recommend Nidecker over the Catek Freeride 2 Pro Evo as they are a better mix of performance and ergonomics/comfort.
