I just picked up a used D3...moving away from my D7000 to take more sports photography of my kids. I have a 70-200 F2.8 and am so excited to get started. Looking at the Nikon website it says that the Sandisk extreme Pro UDMA6 at 90mbs is the fastest I can go...does anyone know if the 160mb works? The Nikon website hasn't updated the recommended CF cards in a year so wondering if I can go faster?
