Shane,
I don't believe that it's a rubber mat under the Jico leather mat in that image...?
It looks to be more like a rigid plastic mat like the Achromat...?
I have friends who like to use a leather/suede mat on top of a rigid one (especially metal) like the Cu180...in combination, the two mats can often ameliorate any stringency in the upper harmonics...
I really can't imagine using a leather mat on a ribbed rubber one...but hey....you can certainly try it...๐
