If the situation is so momentary and dynamic then it would preclude using EC as well. It comes down to what you're more comfortable doing.
Most of us would agree that shooting manual and chasing the needle is stupid, but that's exactly what you're doing using auto modes without riding EC.

I've even been known to mix auto ISO into the equation when things get tough or point the dial to the green box when letting others try the camera for themselves.
About EC and ISO. I gave this answer to gug's question in a G-series thread (Equipment subforum):
It depends on what you're doing. I have a G15. I use Tv and Av often. When controlling depth of field is important, Av is useful. For a fast shutter speed because the subject is moving, or a slow speed for a long exposure, I choose Tv. M also serves in these situations, but it takes longer to set up. For example, if I'm in public in daylight and I might want to capture a scene quickly, I'll leave the setting at Tv, 1/125, which is fast enough for hand holding, and maybe EC = –1/3 or –2/3 because the G15 tends to overexpose. ISO on AUTO. Then the camera is as close to ready for the average situation as I can get it in advance.
On the G15, EC is easily changed. You don't go into a menu, you turn a dial on the top. I assume that this is the same on the G16. In Tv or Av mode, adjusting EC is a quick way of changing ISO and the other parameter that you didn't specify--much quicker than changing ISO and the other parameter directly. In a situation where I need to act fast, I take one shot and check the LCD screen. If the image is too light or dark, or there are significant areas of blown white, I adjust EC and reshoot. Looking at the histogram is useful at this step, too.
