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.

Not sure which Technics rubber mat I had with my SP10mk2, but also stunk. Every mat I tried instead was an improvement. I tried also the suggested modest priced mats I could borrow or buy including Herbie's Way Excellent II Turntable Mat, Funk Firm Achromat, the Boston Audio mat(mostly acrylic) which is the plastic one with the black raised dots that actually lifts the LP off the platter, a couple of spongy, vinylish ones that I don't recall brand and ultimately the copper and stainless steel mats that were head and shoulders the best on my table. I tried them all with 5 or 6 different center clamps & weights ranging hugely in design from the light & affordable Michelle to the heavy & pricey Stillpoints. For my money a $200 custom made 4kg SS 8mm thick mat and an old Micro Seiki center weight were the way to go. 
For the price the Herbie's mat was excellent, but if you get one be sure to order the proper diameter as there are versions just a bit to wide that interfere w/the lip on the edge of the SP10mk2 platter. Cheers,

Lew, yes I did. Used it that way for about a year and a half before I sold it as I downsized for a relocation. Never had a problem. Our pal, dgarretson, gets partial credit / blame  :-) for helping me down that path.
Those who heard it heard how it could be a good thing. 
You can see pics here on the site of the man who made it.
