Is that the latest version of the 3G D.A.? That has reportedly similar tracking compared with a 3.5G D.A.I currently have a Death Adder 3G, RAT 7, and a new G400 that I just bought. The tracking on the Death Adder and G400 is definitely better than the RAT 7 however, the RAT 7's build quality is better and I love the thumb wheel. I just wished Mad Catz used a better sensor than the Philip's twin eye
