JET Method

Tips for Selecting Reference Tension

Twenty-four hours after stringing a racquet the overall stringbed tension will measure at least 4 – 6 pounds lower than the tension that was originally set on the machine. (Often more)  After 1 hour of play there will be a further loss of tension of at least 2 pounds.

The JET Method of stringing progressively increases the overall string-bed tension to at least 2 - 3 pounds higher (for a 16*19 string pattern) than the SET Tension on the machine and up to 5 pounds higher (for a 18*20 string-pattern).

Therefore, to obtain a similar overall string-bed tension when using the JET Method, the Reference SET tension should be reduced from 7 to 10 pounds depending on the machine and the string-pattern. The Reference SET Tension on the machine is much lower, but the feeling of stiffness in the string-bed will be quite comparable. The vastly improved comfort, power, control and spin, as well as the capacity to hold tension and maintain an initial playability for much longer than usual stringing methods are the most evident advantages of the JET Method of stringing.

Below are some general observations and advice  for players using L-TEC strings strung using the JET Method:

- In general, we advise not to exceed a tension of 52 pounds as a reference tension

- Midplus racquets with a pattern consisting of 16 main strings  tend to perform well with a reference tension of approximately 44 lbs

- Midplus racquets with a pattern consisting of 18 main strings tend to perform well with a reference tension of approximately 40 lbs.

- Oversize racquets should increase the recommended midplus tensions by 4 pounds.
