O'Brien Paradigm Binding Qestion?

Here is what I'm running into when mounting my ronix ones to the board, the binding is baseless so the insert sits directly on the board. Well the board has 2 distinct indentions running along the entire board, so when you put a baseless binding on the board you can feel both of the indentions through the footbed. So my question is has anyone run into this issue or advice on what they have done to solve the problem.

I laid up a carbon fiber plate tonight and tomorrow i'll cut out the shape of the binding on the plate and use it as a spacer plate under my binding. So i'll see if thats going to work out or not. I'll keep yall posted if it works out or not.
