I shoot almost exclusively handheld with the 70-200mm and have not had a problem with a shutter speed that turned out to be too slow.

In fact, there's a rule of thumb out there that if your shutter speed is the reciprocal of your focal length (i.e. 50mm, 1/50s; 200mm, 1/200s; etc.), your shutter speed will be fast enough...
I'm going to have to agree with Chris on this one. As long as it's sunny (full) I never go above ISO 160 using a tripod and when handheld and I don't see any reason for anyone to go above 200. The shutter speed is fast enough unless you have a real problem being steady. Of course when the sun is gone, everything changes.
