“理论上任何拍子都可以用一条线，但是为了延长拍子寿命，横线总要从头向拍喉方向拉（因为拉线会使拍子变形，而拍喉最稳定，变形不严重）。所以有些拍子要横线、竖线分开穿（≥4个结）。”
原文如下：
In principle any racquet can be strung using one piece of string, but to maximize the life of your racquet the cross strings should always be strung from the head to the throat (during stringing the frame is deformed and because the throat is more stable the deformation is not as high). So for some racquets it is necessary to string and tie the mains and crosses separately (-> 4 knots).

判断拍子是one-piece还是two-piece，主要看拍子的竖线和在拍喉位置上的竖线多少。如果竖线是16，而拍喉上的竖线是8；或者竖线是18，拍喉上的竖线是6的话，使用one-piece。如果竖线是18，拍喉上的竖线是8；或者竖线是16，拍喉上的竖线是6的话，使用two-piece。
原文：Now how do you know which method you should apply to a foreign racquet? You have to know two things: first the total number of main strings in the racquet, second the number of main strings that are in the throat. Use one-piece stringing if the racquet has 16 mains and 8 among them in the throat, or 18 mains and 6 among them in the throat. Use two-piece stringing if the racquet has 16 mains and 6 among them in the throat, or 18 mains and 8 among them in the throat.
同时，穿一条线的时候（one-piece），横竖线的磅数也应该不同。一般是横线低2磅。
