Very often we talk about 2 knots or 4 knots stringing method.
We tried to compare various types of stringing by comparing a 4 knot stringing with 3 types of 2 knot stringing:
- ATW Universal (Wilson box)
- ATW Liam Nolan box
- ATW 3+3 Jay Schweid box
In the same way we have added 3 types of patterns considered “unorthodox”:
- pattern with 2 knots starting from the center and horizontal from the bottom to the top
- 2 knots pattern starting from one side for the vertical ones and from the bottom up for the horizontal ones
- 2 knots pattern starting from the center, pulling a string every 2 passages and horizontal from the bottom to the top in the same way.
From the experiment conducted directly stringing a PURE DRIVE at 24kg with various solutions, using a monofilament string SIGNUM PRO – poly plasma 1.23mm gauge we have obtained some interesting data that will allow us to compare from diagram to diagram.
THIS COMPARISON DOES NOT WANT TO DRAW UP ABSOLUTE RANKINGS OR EXPRESS JUDGMENTS OF MERIT BUT SIMPLY TO HIGHLIGHT THOSE THAT CAN BE CONSIDERED PRO AND CONS OF THE VARIOUS METHODOLOGIES AND HIGHLIGHT THOSE THAT ARE THE CONSEQUENCES RESULTING FROM ONE MODE OF APPROACH RATHER THAN ANOTHER.
The tests conducted were carried out following this protocol:
- evaluation of the tension of the racket just strung
- vibration frequency of the freshly strung racket plate
- evaluation of tension loss after 4-6 hours of non-use
- vibration frequency of the plate after 4-6- hours non-use
- evaluation of the static deflection rigidity of the string plate at various points
- Estimation of racquet sweetspot and uniformity of stiffness.
