Static electricity pulled the rubber mat right off the Turntable!

I have wall to wall carpeting made of some kind of synthetic.  
The thing is, I have two turntables in the same room.  The Dual and a Bluenote Bellavista Signature and that produces no static at all.  Of course the platter is not aluminum like the Dual's.

I have a Dual CS-5000 that causes records to amass static.  It has a grounded bearing/spindle but that doesn't seem to help.  I replaced the stock mat with a Herbie's Excellent mat and this helped some with the static, worked better with the sound.  A definite step up from the stock rubber mat which to me sucked the life out of the music.  I tried a cork mat and that didn't help either.  

So, I use a carbon fiber brush before and after play on each side and do a quick blast with a Zerostat after the second side is played.  The odd thing is that I don't notice as much static until I play the second side then lift it off to put it back in it's rice paper sleeve and I hear that crackle and of course any dust in the air immediately attacks the record before I can get it back in the sleeve. The Zerostat seemed to help with this phenomenon.
