Burton channel pucks are based on the Voilé interface system.
You can use Voilé interfaces with any snowboard bindings that have a 4 hole system (Burton reflex bindings come with the required discs). The classic binding from Burton is perfect in this case as it has a one piece baseplate.
The best solution however is to use a binding such as the Burton 'Hitchhiker'. This binding already has the correct interface in the baseplate and saves you a lot of weight and hustle.
