Turntable Mat question


I read a turntable Mat comparison which mentioned that although there are many different choices,
some audiophiles will use LP Records as a mat
What is your opinion about this ?

@browndt So do you place the LP directly on the metal platter on your Prime Signature? I have a Prime Signature too. Do you use the included record weight? How about an outer ring?
I’ve tried a lot of mats on my SL1200, and ended up going with a Herbies Way Excellent ll Mat. You can get them in basically any diameter and thickness to suit your particular turntable. 
Herbies Mats are the way to go. I am using the Grungebuster Mat with a Ceramic platter turntable with excellent results. You can't go wrong.
@hifijunky and @technick What is the optimal thickness for a Herbies mat on a VPI Prime Signature turntable? Thanks.
