Oops, my bad. They do, indeed, end at the throat so ATW is an option.
See, it confused me,too.
I, too prefer to do 2pc when the mfr says 2pc only.
I choose to follow the USRSA recommendation; "When given the choice to do 1pc or 2pc; use the method that strings top to bottom"
I've taken to using ATW/Box patterns for old Pro Kennex and Donnays, etc., but I'll usually use 2pc on Babolat and Wilson.
I do wish that all of the stringing sites would get on the same page as to how to designate the holes.
