I don't know much about the Taipan yet, but the Deathadder has a good sensor and does work as a claw grip mouse, at least for me, if not you could check out the Lachesis or Abyssus, although the Abyssus is more of a fingertip mouse.
I haven't heard much about how the sensors on the newer Razer mice are so if you're going for something like the Taipan you should do proper research first. The Deathadder probably has the best sensor of the bunch, but you should try to hold one if you know someone who owns one or in a store, just to see if you can hold it comfortably.
The G9x still has the acceleration deal so that's a no go if you want a sensor without it.
So, top of the head list; Deathadder, Lachesis and Abyssus. Might want to look at the CM Storm Xornet as well.
