Playing a first person shooter with another man's mouse is like brushing your teeth with his toothbrush: it will get the job done, but might give you the heebie jeebies. Still, if you had to use someone else's mouse, using Jonathan "Fatal!ty" Wendel's is a good bet.

Wendel is the closest thing the video game industry has to a superstar and now Creative Labs has designed a mouse just for his particularly gaming style. ExtremeTech has all the details on the Creative Fatal1ty 1010 Mouse, but it sounds like a great mouse for gaming: Small, adjustable weight, and with a variable resolution of as high as 1600 dpi. Granted, Wendel's personal preferences may not match your own, but the guy clearly knows his way around a mouse.

(I still wouldn't use his toothbrush.)
