I have 2 sets of those hardboards to choose from. All are warped, one set worse than the other. It would be easy enough to cut out a new set that would be flat. Substitute material is my delima. I have some corigated polystyrene ( was a store display, Coca-Cola ). I dont think it would warp. It is about 3 times the thickness of the factory hard board though.
So other than you prefer Pepsi, what do you think ? I have 4 hours to make a decision. TIA to FABO
