The face on my Saw Stop ICS table saw is not "flat", which has caused some issues with certain blades. In addition, I had a misshap that caused a board to make a slight gouge in the face. At any rate, I need to replace the stock face. So, I'm wondering I anyone else has replaced their fence face, and if so, what material they used? I am considering:
-Phenolic face Baltic birch plywood
-MDF with shellac and wax finish

thanks
