I have it, and have used it on numerous occasions to shoot hockey from the stands. It is light and easy to hold (I have the tripod collar on mine, and rest the foot on my left hand). The best part about it is that in many arenas you are limited to a lens of no more than 6", and that lens is right at 6" mounted. Also, because it's black, it doesn't draw the same attention as the 70-200.
Here are a couple of examples.
For sports, you need high speed anyway. IS doesn't do much good there. If you're going to be shooting things that are far away, a little bit of movement makes a big impact. So, you'll need to either work on your form to produce less shake or use higher shutter speeds. At f/2.8, that shouldn't be quite as hard as the consumer grade lenses in this range.
Great images! Do you find that you have to shoot at high shutter speeds because of the lack of IS to obtain sharp images shooting hand held?
