I am using Woodland Scenics foam roadbed exclusively on my new layout, although I do have a number of sections of Midwest cork roadbed still available. I have used the Woodland Scenics product on other layouts in the past (various scales), and I really have been quite satisfied with it. Very easy to lay, even in tight curves, if necessary, and easy to work with after it is laid; or even to take up and reposition once it has been in place for a while. Can be painted and/or ballasted, and it seems to hold up well. I will be ballasting the track on my new layout--a task I really don't look forward to-- once everything is in place.
Like most others, I used cork roadbed for a good many of my earlier layouts in Z, N, HO, O, and Large Scale. No complaints from me, but I guess I never had any of the Midwest product with rubber mixed in. Didn't even know they were doing that.
