Mode One is for still photography. Mode two is for panning. There is a considerable difference with IS than without IS so keep it on if you can. The batt. issue I haven't really noticed as I have the grip.

Well i use IS on all my lenses and have noticed no issues withbattery life at all.
I also use the grip on my 20D and get around a full day out of a pair of batteries which will get me 2000-2500 shots.
Like everyone else mode 2 works well at airshows.

I always leave it on. I have not noticed a significant reduction in batt life although maybe there is a slight reduction.
Personally, I have not gotten the most out of this lens.....yet. I think it may be me, my skill in shooting steady and using the correct settings. I do have a lot of good pictures, but haven't gotten the "money shot" yet, such as Darren's shot above.
