Pitch Animation - Part 2

So I have been testing outlining in Illustrator CS5. There is a new brush tool that is awesome. I just need to figure out how to make the line weight more consistent. The stroke weight started really thin when I first started outlining, and then got thicker and thicker at the end. Maybe I was pressing to hard or maybe a setting I messed up.  There is a few problems with the animation a couple pops in the movement and some flowing issues with the movement. Other than that not to bad for about 5 hours of work.
