Got a couple of question regarding the mouses that I have been looking around to replace my old deathadder. Is there any mice from Steelseries that meets this criteria:

1. Suitable for FPS
2. Claw Grip (I also use Palm grip when not gaming)
3. As large as DA

Would also prefer if a mouse would not gather dust as easily as the sides of a DA. Mouses that I have in mind are SS Xai Laser. Would Sensei be better?
Looking forward to your advice
