Razer says that you can "switch between high DPI close-quarters fighting and low DPI precision shooting," depending on whether you're using a handgun or a sniper rifle, for instance. You can swap in clutches of two different lengths, depending on your hand size, or install a rubber cap if you don't want to use the clutch at all.
Otherwise, the Razer Basilisk (yes, Razer names its mice after reptiles) should be a solid gaming mouse, particularly for FPS games, thanks to the 16,000 DPI sensor borrowed from the Lancehead Tournament Edition model. It also has a dial that lets you adjust the scroll wheel resistance to fit your preferences. It's now available at Razer's online store for $70.
