Foam with a grade below the track question?

[railbuilderdhd]

I was getting an order for more WS risers then I read a post on another forum. They had a great idea of putting the cut foam under a clean foam sheet for my incline. I tried this last. I gut and I think it will work great. The last step to getting this correct will be the transition from flat to incline and back to flat.

I'll post photos as soon as I get some.
