Look at some of the pictures in Snowboard Equipment -> Boards -> Show off your setup that you're using for the 10/11 season.
You'll see that very few people bother to match brands. A lot don't even worry about colours. The important thing is to have your boots (or one of them anyway) with you when buying bindings, if you're at all unsure.
I'm sorry. Was I talking while you were interrupting?
