Audioprism CD Blacklight mat?

Does anyone know the difference between the regular CD Blacklight mat and the one meant for the Stable Platter transport? I have an EAD CD 1000 that has the stable platter transport and The Elusive Disc is selling both CD Blacklight versions BUT the Stable Platter version is priced at $35.00 and the regular one almost half price at $20.00. Just wondering what the difference might be. A friend once brought over the regular one but the hole in the center was a little small to fit over the spindle on CD platter on my EAD. With a little trimming it would work but maybe there are other differences. Any thoughts?
