Hair Brush(ology)

I saw this chart on Pinterest today, and it definitely got me thinking... I am pretty hopeless at styling my hair beyond it's natural tendencies and inclinations. I know how to straighten or curl it, and I can do a braided headband like a pro, but I never use a hairdryer so brushes aren't exactly the #1 tool in my arsenal. In fact, out of all of these brushes, I exclusively use #5, a wooden paddle brush, though mine is this one from Aveda. How many of these do you guys use? Do you use different brushes for different styling maneuvers? Fill me in!
