I'm going up tomorrow to Big Bear and i've just received my burton bindings yesterday. I noticed it was the 3 hole and i went to my local SB shop and got a 4 hole. I went into put in my base plate and bindings and noticed that my screws would not fit my board. I have a k2 zepplin. My question is what size does a zepplin need for a screw or any standard snowboard.
