I can't make any sense of Stringway's tension advisor

    My first problem is with the classification of strings. They have S1, S2, S3, and S4. They describe them as follow:

    S1: Comfort
    S2: All-round
    S3: Spin/ playability
    S4: Spin/ durability.

    Okay, so I was thinking S1 will be multis, natural gut, etc. However, in this chart they provide, they list Spiky Shark, ALU power, and Signum Pro Tornado as S1 strings! What?

    http://www.stringway-nl.com/en/TAonline/ELONGATION TESTS CLASS 10-2011.pdf

    After completing the questions, it suggested I use S3 or S4 strings. The only strings listed in those categories are 1. Obscure and 2. Not much different than the S1 or S2 strings.

    Am I missing something or is this just way off?

    Hi HunterSt,

    Hereby a much newer list with a lot of strings in all categories


    And a little more explanation:
    The strings are classified based on the elongation character and this is what the player feels.
    The more the string stretches the more convenient it feels for the player when he hits the ball.

    We measured the elongation figures of all the strings in the list.

    And from the list you can see a number of remarkable things:
    - The elongation does not depend at all on the gauge, there are thin string which are very stiff and thicker strings which stretch a lot.

    - There are monos in all classes so monos are certainly not always stiff.


    As you can see the elongation is divided in elastic and remaining elongation.
    The biggest difference between strings is not in the elastic but in the remaining elongation.

    The elastic elongation is the actual elasticity which provides the power and recovery after a spin stroke.
    The more remaining elongation the quicker the string looses tension during play and during stringing.

    This means that a more convenient string will always also loose tension quicker.

    Therefore the el/tot figure is actually a quality index for strings, it is the amount of elastic elongation in the total elongation (column Q).

    The Tension Advisor is already very old we made this system for Rucanor in1989.
