Need correct balance shoe tilt

Thanks for posting. Your shoe looks like an old, discontinued version of the 15-118. I think ours can still work for you, so check it out. As for removing it, you should be able to simply pop it out of the cutout with a screwdriver. There's no trick to it, really. See the videos below for a visual example of how we do it:

As long as the size is the same, you should be okay. For the 15-118, the cam slot has an overall measurement of 5/16" wide by 3/16" high.
