As for me, I like the red ones.

Many of you know I build cars for Toys for Tots. Hundreds of them each year. My cars are our "Volkswagon" design, and are built from 2 X 4 stock. Lowes's "Top Choice" lumber in the 2 X 4 size is imported by Klaustener Lumber from Germany. By searching the stacks, I find the 2 X 4's I want. They have to be as clear as possible and as dense as possible. I often find studs with 20-40 growth rings to the inch. They are usually red in color as they come from the center of the log. This helps me find what I want quickly. Just look at the end of the bundle, and if I don't see red, I wait till next time.
