My personal zone generally starts with a round or two of F-Zero or Unreal Tournament at 130-150%. Once I get accustomed to those speeds, I've been kicked for aimbotting because I tend to enjoy weapons like the lightning gun, and am reasonably accurate on even bad days. It's like playing Halo instead of UT - people just float around, comparatively. Keeping track of a handful of people in a firefight becomes easy.

I wish I could switch it on and off as needed, but it definitely drains you more quickly, and gets harder to achieve after the first round or two. But it's exhilarating.
