Technics SP series mats?


Other recent discussion here discusses replacement mats for DD tables, including the SP series.  However based upon photos showing different ring patterns of stock Technics mats it seems there may have been a few different models over time.  The mat with my SP-10 Mk2A is SFTG172-01 while the mat with my SP-15 is SFTG015-01.  The ring pattern appears the same but the first one is heavier, thicker, and stiffer.

So does anyone know how many different mats were provided for the SP series and if any one is recommended over the others?  Perhaps more important, for those who have tried different mats did they offer sonic improvements over any of the stock Technics mats?  I realize this is difficult to answer unless someone tried more than one model Technics mat.

I use a Herbie's Way Excellent II on my SP-15 and its significantly better than the stock rubber mat. Seems like it would be worth a try on the higher end decks too.
