My experience has been, as long as you are pulling the wire out of a Cat 5 box it keeps coming but if you throw in in the back of the truck and bounce it around a little, the next time you have a bird's nest in there. No matter what, the last 100 feet is coming out in a ball.
I am experimenting with a box as we speak. It has been sitting undisturbed on a shelf in my shed and I just spool out what I need as I need it. So far so good about half way in. I am pulling everything in raceways so getting the length right is pretty easy. I got in the habit of writing the length of the raceway on a label when I install it. (and it is fresh in my mind)
