I am just learning to string, and understand ATW as stringing one piece with the crosses going top to bottom. I was wondering if you can avoid this by alternating the starting position so that the mains finish at the head so that your cross starts at the head. Also what is the purpose of pulling from the throat when you have 8 mains in the bridge or pulling from the head when 6mains are in the bridge? Wouldn't all racquets with 16 mains have the mains finish at the head if you started pulling from the throat? Thanks to all the posters for the previous tips, this board is great.
