Rendering Intent (which to use)?

I thought I had this figured out but as always I put the cart before the horse. I ordered a Spyder3 Studio SR and then started to do a little in depth reading on how to use it. What got me was them (Datacolor) saying to use "Saturation" as the rendering intent with the profiles created. I was like, wow, after all of the experts saying to use either "Relative Colormetric" or "Perceptual" and no one could make up their minds on "black point compensation".

If anyone here uses this setup please share your thoughts and practices.

It's common to use Saturation or Absolute Colormetric rendering intents when creating a custom profile. Any custom profiles I had made for me were done with Perceptual rendering intent. Experiment. Just be sure to use the same settings when printing or softproofing as when you printed the target image.
