I discussed in "Fireweed and Cook Inlet" subject the use of Linear Profiles. 
Namely to improve the shadow/highlight recovery.

This is a repository of linear profiles for various cameras already created if 
one has interest in trying one. Also a description of linear profiles and why 
one might want to use one:

- More flexibility in Lr/Cr since sliders often provide additional room for 
adjustments.
- More predictable adjustments in Lr/Cr since the image responds better to 
slider movements.
- Better shadow and highlight recovery.
- Richer, but not overly-saturated, colors.
- Hue, saturation, and luminance adjustments work better.
- More pleasing RAW conversions.
- "Expose-to-the-right" has greater potential since applying a linear profile 
darkens the image.

Moose had interesting comparison of NR in "NR vs NR". I found this video on 
using DXO PhotoLab 4 or DXO Pure Raw as a workflow for noise 
reduction/sharpening with Lightroom or Photoshop:

He also uses one of the linear profiles in Lightroom.
