    Hi guys

    I have had several racquets that were professionally strung at different tensions (same racquets, same strings). After about 6-8 hours of play they all come down to around 8.2 - 8.4kg's, regardless whether they have been strung at 8.7, 9.0 or 9.4.

    I have no idea what I am doing wrong. One of the things that I could think off, is that the stringing machine doesn't pre-stretch correctly?

    advice would very welcome
    kind regards
    P

    BG65 will lose tension regardless of how you string them.

    the only possible remedy is to extensively pre-stretch them (not on the machine), but that takes many hours.

    and i believe the tension loss is much more than the 0.5kg to 1.2kg range that you specified. even regular string will lose 1lb (~0.5kg) unplayed and then another pound after first time playing. BG65 will easily lose another 2lbs.

    Thank you so much for your fast reply Kwun.
    I am glad that I'm not the only one who has come to these conclusions :).
    And yes I also agree that they loose even more of the tension.

    So, the next logical question for me would be:... what string should I switch to?

    kind regards

    Usually adding two to three extra pounds to your reference tension for BG 65 will make up for the eventual tension loss. I would recommend BG 65 32 lbs or over.

    What the hell are you thinking recommending something so ridiculous to a person who usually strings at 9kg (20lb)? If that guy has an older or cheaper racquet, 32lb will cause the racquet to cave in on itself. Even if the racquet didn't break, recommending someone to increase their tension by 12+lb is just a terrible, terrible, TERRIBLE prank.

    Worst post of the year!

    Polder,

    I prefer playing @10kg. The only way to have this tension after 10h of play (with BG-65) is to string at around 11kg.
    BG-65ti will keep the tension better, but the break easily.

    I'm not that experienced, but this works best for me.

    Who strung your rackets? Speedy?Ron?

    It's strange how high rackets are strung in other countries, in Belgium -> 18lbs for beginners, and good players aren't going higher than 25lbs except some...
    Would like to test a racket at 32lbs though

    Can't tell is serious or sarcastic.

    From my reading of BC, Mr. Pete LSD always strings and talks about using these tensions. Its nothing new from him. He does it with everyone. There is no need to become overly enraged over it.

    As for Polder, I would recommend Bg80 if you dont mind switching strings. It seems to hold tension pretty well. Loses only 2 pounds or so based on my experience. However, it has lower durability.

    not really. most people here also don't get over 25lbs. only in Pete's household where tension starts at 30lbs. ;)

    dude. if you make comments like that, some people reading it will think you are serious and follow it.

    best case is they might have a broken racket, worse case is they will get injured and never be able to play badminton again.

    be responsible on what type of joke and how you make it.

    A couple of things things to try:

    hand-prestretch before stringing (around a doorknob, I mean - pull until all the slack is gone from the string),
    a new knot and/or tightening technique (look at YULitle's Youtube videos).

    If neither of these works, it might be worth stringing to, say, 10kg, then leaving the racket for 24 hrs before use. (If you can pick the racket up and pat the strings during the day, even better.) IME string jobs usually stabilize most of the way down in the first 24 hrs whether played with or not.

    I am second for the extra 2-3 lbs solution. This extra 10% tension will reduce some of extra tension loss. But no thanks for 32lbs, my old body can never take that abuse. :-D

    SO THIS IS NEWS TO ME LOL!

    No wonder when I get my BG65 strung at different places @ 24lbs it feels so funny. When my coach strings mine, he prestretches it before stringing so its actually 24lbs...

    So if I want 24lbs with my BG65 to be my end result and I am assuming that my stringer doesn't prestretch, how tight should I ask for it to be strung?

    Difficult to answer. Most strings drop tension fast and then they slow down but still drop. Depends on how much time you wait and what ratio and what type of machine. If you want real 24lbs I can say that you will have it for just a few hits and you don't know when this point came. I would choose the tension which feels for the most time comfartable. I guess if you go for 24.5 x 26.5 you will have a long period where the string is close to 24. You need to experiment. If 23x25 without PS is too fast spongy the logical consequence is to go next time for 24x26 and try it. I cut strings after around 3-4 weeks so I'm the wrong person for this experience, but I can say that every string become after a weeks weeks dull and unlively regardless which tension. Even a 32x34lbs job become after a few weeks unplayable. Even if you aim 30lbs. Just my experience.
