There are so many variations of ATW.
What's your preference and why?
Also, is there ever a time that you would do ATW for a Head or any other racquet that ties off at the head?
If so, how to avoid bottom up? String the 1st X with the short side?
Long ago, a client got mad at me for not doing his Head racquet with 'only two knots'.
Of course, he was also convinced that the knots would slip.
