Randy:
Want to warn you about "pushing" profiles around too much--you can be
asking for trouble, such as posterizations, etc. 

Small adjustments are alright, but for the most part, I like to let
the profiles fall to the default, and use adjustment layers on
individual files to achieve precise results. After all, every image
will vary, and creating a custom profile for one, just creates a
problem for another. Unless you are photographing people under the
same consistent conditions, I don't think you really want to monkey
with profile changes.
