Decisions with programs use

After looking through a few forum threads, I've decided on which programs I'll use for different works.

Corel Painter 12 - I'll use this program for realistic paintings, due to the many MANY brush type selections. If I should ever do rotoscoping again, I'll use Painter for this as well.

Photoshop Elements 8.0 -  I'll use this program for landscapes and touching up such as filters and little touch ups. I may occasionally do artwork pieces in Photoshop (that aren't landscapes) for when I want a texture background.

Paint Tool SAI - I'll use this program mainly for line art and possibly many of my sketches and coloring.

Though I've planned out this as such, I will most likely switch between Photoshop and SAI, since I'm currently still going between both programs trying to figure out which I like best for what.
