Timberline, that's my next step. The shop I took my board to for wax/tune didn't have any and obviously said "You are going to have to buy new bindings" to try and initiate a sale. There are one or two others in the area I'm going to call and see if they can hook it up.
VKNY, yeah, I'm pretty sure that's what changed. These are 4.5 inches diameter, not sure what the new ones are; but I'm pretty positive that they are a little smaller.
