For sale here is my Burton Split 166 with a Voile interface. This is an older model of Burton's back when they made their own interface, but I removed it (it sucked) and installed the Voile instead (much better). The board has seen plenty of use, but is in good shape and rides really, really well.
Do you still have the old burton interface model that you took off your Burton board? I am in need of those s interface base plates that mount to the bottom of the snowboard binding. If this is similiar to what you have, hit me back and I could send you a email of my splitboard setup to verify. Thanks
