I too use the VPI provided protractor on my Aries 2/JMW 10.5 and it seems to work just fine. I have checked the setting with the DB protractor and the setting is confirmed by that one too so at least these two are congruent. Another option is to order a Wally Tractor that is specifically made for your table. It uses reflection at two points and is supposed to be very accurate. Last I checked these go for arounnd $150.
