Fellow stringers often ask me what I think about certain racquet service topics. I will periodically post position statements here. Be sure to check back regularly as positions often change as new technologies and techniques emerge.

1-piece versus 2-piece stringing, also known as 2-knots versus 4-knots.
Neither method is better than the other, nor does either method produce a better result than the other. However it is important that stringers remain proficient at stringing with both 1- and 2-piece methods. Therefore -
There are several exceptions.
Copoly monofilament strings for junior tennis players.
Regardless of age, for junior players who consistently break multifilament strings, the use of copoly monofilament strings is a viable option, starting with the thinnest, highest elasticity copoly installed at the lowest tension that compliments the frame and is suitable for the player’s skill level. Using a reference tension that is lower than the frame specifications is acceptable. The stringer should communicate the pros and cons of copoly strings to the parent and be open to feedback from the parent, coach, and player.
Use of plastic bags to store and transfer finished racquets.
CCS supports the use of low density polyethylene (LDPE) bags to transfer finished racquets to players. Players should be encouraged to reuse bags for future drop offs, or to recycle them through their local public works programs. Multiple racquets for the same players should be placed in the same bag whenever possible.
Tie off knots and location.
Use of a starting knot to begin crosses.
CCS supports the use of a starting knot to begin crosses. In terms of functionality, the end result of using a starting knot instead of a starting clamp is the same.
Use of a starting clamp to begin crosses.
For aesthetic purposes only, the use of a starting clamp is the preferred method to begin crosses. This ensures all knots on the completed racquet are the same. To avoid prolonged clamping of the top cross string, the top cross should be tied off as soon as the closest fixed clamp becomes free. Often this is after the third cross has been clamped off.
Use of starting blocks, pads, or similar devices.
The use of starting blocks, pads, or similar devices to protect the segment of string that wraps around the outside of the frame is not necessary, regardless of the type of string. However, the use of these devices to prevent the starting clamp from scratching the frame of the racquet is encouraged.
Measuring stringbed dynamic tension.
Dynamic tension (DT) is a data point, not the data point. A handheld DT device or a downloadable racquet tuning app are no comparison to the accuracy of the stringing machine, the skill and consistency of the stringer, and the feel of the racquet during play.
Use kevlar string when creating a bridge with a starting clamp or with a tension calibrator. This is the only practical use for kevlar string in tennis today.
