SP10mk2: OMA Graphite plinth vs.Dobbins plinth

According to the price lists they are in one category, but anyone could comment on quality/performance? At the moment i use big Teak Wood plinth (just $750) custom made in Taiwan for my SP10mk2. Looking for upgrade in the future. I use my sp10mk2 with Reed "12 tonearm now. Doest the plinth actually makes a big difference in sound? My stand is well damped with glass, metal and sarbothane in between.

1) Oswald Mill Audio graphite slate plinth (single layer) $2750, double layer looks fantastic but cost $3500

2) Steve Dobbins famous custom plinth cost $2650 including three Stillpoints feet and automotive show quality paint in black or white. Design has changed many times, still hard to find any current plinth picture online.

I know there are Albert Porter's and Artisan Fidelity quality plinth available, but i don't like the design (i mean just how it looks) for SP10.

chakster, if you are curious, Technics offered at least three plinths for their SP-10 series of motor units.  

The first, for their initial SP-10 was a basic box frame.  With the introduction of their SP-10 Mk 2 came the SH-10B5, a 38.2 pound composite obsidian plinth.  The SH-10B7 was similar but weighed nearly 42 pounds.  I thought there was another option but can no longer find reference to it on the Vintage Technics site.

Your teak plinth certainly looks nice, whether optimal for sonics or not.

chakster, do you, or others here, have any experience with the AT-666 mat?  It was designed to add vacuum hold down but I recall reading of some using it just as a replacement mat.  Raul in fact recommended it with the Technics SP series as a mat only.  It weighs 1.4 kg.  Also may be easier to find than the CU mats and for much less money.

With some of these heavier mats I'd be concerned not only with start-up torque but possible excessive bearing wear.
