Which camera calibration profile do you use for your imports?

Question

I have a Canon camera, and have always just imported with the LR  settings left to Adobe default, including the Calibration panel set to  Adobe Standard profile. Sometimes it provides a satisfactory starting  point, other times not. Since reading in another topic's posts  concerning importing with other profiles (and setting them as a new  import default), I have tinkered around with trying this out. Just  curious how others handle their import settings. Do you leave everything  at Adobe default (basic, tone curve, detail, calibration)? Or, do you  reset to a  custom default? What are the actual settings that you use  and your reasons why. And, do you import with lens corrections enabled.  This information would be a big help in gaining a better understanding  of this aspect of LR.
Thanks

Rob Cole wrote concerning Lens Correction settings:
I only do 80% of vignette correction, and 0% of distortion correction by default, and revisit that decision after importing, but nothing sacred about it - plenty of people use 100% for those too and do fine, or use their own pet numbers...
Yes, absolutely use Lens Correction along with Camera Profiles. Like Rob said, "No reason not to!" But there are some considerations. You may like a little vignetting in the picture and 100% pretty much wipes-out all vignetting. Also, since vignetting correction raises image corner brightness, lens aberrations such as astigmatism and coma will be more visible and can reduce image quality near the edges. It's a trade-off as to what amount to use, which will vary dependent on your lens corner performance. I use a default vignetting setting of 50% for wide angle zooms and 100% for all other lenses, and only adjust higher if the image benefits from it. Distortion setting in an ideal world should benefit from 100% correction, BUT it can also degrade the corner resolution with wide-angle zoom lense images which typically have high barrel distortion. I use a default setting of 0%, and only use it for correcting images with obvious geometry distortion. Even then I rarely need to use 100% to make things look "normal." Chromatic Abberrations adjustment can safely be used at 100% for maximum benefit, assuming the profile is accurate over the zoom focal range. The new Adobe lens profiles seem to work very well in this respect.
These are great"automatic" tool adjustments to make our less than perfect zoom lenses perform near prime lens image quality. OK, zooms don't have the wider aperature of prime lenses, but the high ISO of today's DSLR bodies give us a lot of latitude to play with!
