In which of your photography is the IS of your 70-200 2.8LII usefull ?

I'm just looking at some older pics of my 70-200 2.8L non IS and all are very sharp, I had version I with IS also which was less sharp wide open.

Just wondering in which of your personal situations the IS is gold for you.
As last time I went to a film festival, I thought I could use IS, but stars were moving, so again not necessary.

That's why I ask examples from your situations, to see if I get in contact with about the same situations and if I really can use IS.
I plan model photography in near future, so for this it's a + allready.

On my 70-200 II, I find the IS very useful while shooting on the longer end (200mm) of the focal length. In fact, I keep the IS on all the time, except when my lens is on tripod.

Panning shots of motorsport (or any panning shot really) This lens specifically has mode 2 just for that purpose

Pretty sure the lens auto detects when it's mounted to a tripod and turns off the IS anyway so you don't have to remember to do it every time. Useful also if you forget to turn it back on when you take it off the tripod.

The only time my IS really gets turned off is when I'm using a tri-pod, purposely shooting at very high shutter speeds to freeze action, or if I'm shooting/tracking a subject that is not moving in an exclusively horizontal direction. IS mode 2 can be a huge help for panning shots.

Other than that, the IS gets used as an added protection against camera-shake in all situations. I have been able to fairly consistently take shots @ 200mm, 1/30 shutter with perfectly reasonable sharpness. IMO, having IS is not a necessity, but it does make the lens much more versatile.
