I typically hand-wind my balls and pull them from the outside. Put a round ball in a bowl, basket, or even a bag and they tend to behave when pulled from the outside. However, there's another world out there!
Some guys like to wind their balls mechanically, make them flattish, and pull them from the center. Sure, they don't slide around so much and pulling from the center can initially be nice, but eventually they're disheveled and misshapen.
What are the advantages/disadvantages of hand-winding versus mechanical-winding and pulling from the outside or the center?
