That would seem to be good reasoning based on simply looking at my pics. However the denseness of the foam even with the two holes (tunnels?) ends up with it being no more compressible than the Ames part without holes.
Interesting to note as I was setting up these pieces to take a pic in the vise and rag, that the two stiffest ones kept wanting to "roll over" sideways while the two GM parts stayed put and compressed easily.
