Watercolor Paper

Okay, here's a question for all you lurkers out there, it's time for you to click on the Comments and leave a comment. We know you're out there. :-)

I spent a lot of time in the art supply store today, buying over a dozen large sheets of watercolor paper for a BIG project I'm starting work on tomorrow. I'm committed to this paper for this project, but is it the right paper for me? The saleslady in the paper department introduced me to many, many flat files of different kinds of watercolor paper. It's not that I'm a moron, I know the difference between hot-pressed, cold-pressed and so on, I'm just not sure what paper is a good match for me...

QUESTION: What watercolor paper do you use?
What brand?
Hot-pressed, cold-pressed, rough?
Poundage?
Watercolor block, pad or sheet of watercolor paper?

Good qualities / Bad qualities about the paper you're using?

Do you ALWAYS use the exact same watercolor paper or do you toss it up a bit?

I am desperately seeking a watercolor paper that I can say, "This is the watercolor paper I will marry!!"
But I haven't found it.
I sometimes think I've found it and then I break-up with it and never make eye contact with it again.

Come on, give me some suggestions and advice.
