”Form what Ive gathered so far, seems softer matts enhance bass, warm but can cloud detail where as hard matts enhance detail, treble.”
This squares with my experience.
Here is a discussion on acrylic platters with no mat containing some conflicting advice:

The owner of a local HiFi shop once told me that I should use a record clamp (not a weight) when placing a record directly on an acrylic platter to help address the slipperiness you mention and improve coupling. Something like this, or the $50 little plastic bit that is marketed by Clearaudio.
