I try to preset for each situation too. It is very valuable. In fact I started a thread about it today http://www.apug.org/forums/forum48/1...nting-bit.html

So i have a question, what ISO?

It's an honest question, not flippant. It takes all three.

Time and aperture are used to make creative choices, time controls blur, aperture controls DOF.

ISO finishes the equation to get proper exposure.

Im trying to figure out why.
