    Sadly speaking, most people who strictly see stringing badminton racquets as their job and a form of revenue have no care of the proper way of doing things as they will only do things as they see fit themselves. As I have mentioned these "stringers" (who have no care or interest in learning other methods than their own) will always try to maximise their own benefits and the lack of care of using the correct techniques will only allow them to maximise their time saved per racquet string job.

    Time is money, and these "stringers" are mean, money-pinching unethical business people.

    this is what i was told regarding Yonex Certification in the US.

    Alan Kakinami, one of the official Yonex stringers who strings for many of the Yonex badminton and tennis events are in charge of certifying Yonex stringers. however, at the moment, the certification program is still being worked on and nobody (despite what they tell you), probably except Alan, can be called a Yonex certified stringer.

    once Alan has the program in place, then maybe we will see more Yonex Certified Stringers.

    Yonex USA is working on it. Kind of like what USRSA does, have a list of certified stringers so customers feel at easy when taking their rackets to shops

    Yes. I think because the bottom of the frame is wider in length having a lot of tension in the frame causes it to crack i.e. 2005 World Championships. I heard a stringer was going top to bottom stringing 34 lbs broke 3 rackets in a row. went bottom to top, no problem

    Yonex Tennis rackets are supposed to be strung Top to Bottom. Any regular Tennis stringer would normally string from top to bottom, but that because they are trained and tested that way. Any stringer, certified or not, should take the time to know the racket they are stringing. I'm almost willing to bet there are some USRSA CRTs that have never strung a badminton racket.

    But I thought the best stringing method is simply just to maintain the original racket shape with the least distortion, period. +2lbs or 10% more on the cross doesn't have to follow. There has to been tons of discussion about top down and bottom up already, please do some homework before raise it up again.

    ALL Tennis rackets should be top to bottom. ONLY Badminton should be bottom top. Agreed with your statements, but if you look into 90% of shops, their stringers are HS or College guys looking to earn extra money. The USRSA MRT or CS, especially if they are at a private club don't know what badminton even is =P

    I think the 10% theory had to do with 2 point mounting machines. The 6 points help maintain racket head integrity.

    i think there are 2 factor to the 10% theory. one is 2 pt mounting as you mentioned to restore the head shape. the second one is more universal, and that's the zigzagging of the mains string after the cross strings are tensioned. the zigzagging of the main string causes its tension to go up in order for the cross to have the same tension, the cross needs to be pulled at slightly higher tension.

    i understand who the crosses would add extra tension to the mains but arn't the crosses shorter and therefore feel tighter due to their length. so if u use 20/20 yes the mains tensions goes up to 21-22 but because the mains are longer would they not still have the same frequency as the crosses. so would 20/20 give you a more repulsive string bed but would add stress to the racquet?

    I just purchased a used Yonex Racket and it was strung

    The last horizontal string is on the 8th hole counting from bottom, rather than on the 9th hole as recommended by Yonex. As a result, the single string grommet is stretched to acccomodate the extra string.

    Why did the stringer spend that extra effort to run another string beyond what is necessary? Is that ignorance?

    So question is how does that affect the racket performance anyway?

    It adds a stiffer string plane to the racket. Most top players like it, adds more control to the racket, since they generate a lot of power.

    forgot to answer this.

    that's what i originally thought about the frequency. shouldn't the final frequency of the main and cross string be the same for them to have the same response. we went through this a lot in the progressive/proportional tension thread. that means the cross tension should much lower than the main tension, because the length of the cross string is much much shorter (20%?) than the main.

    then i realize something. we should not be looking at the the frequency of the individual string segment. instead we should be look at the frequency of the whole stringbed as a whole. what does that mean? that means that the *density* of the string bed matters as well. the higher the density, the higher the collective tension/frequency.

    to illustrate. a stringbed with just 3 cross/main string will feel softer than one with 40 cross/main string, even if each individual string are the same tension.

    now, let's go back and look at the badminton racket, even though the tension of the cross/main are very close, if we look closely, we noticed that the main strings has a higher density. ie. they are closer together than the cross string. that give the main string a higher collective frequency. which compensate for the fact that the main strings are longer and should have a lower frequency at the same tension.

    i hope that makes sense.

    I totally agree. I would like to eventually get certified as a Yonex stringer.

    yeah makes sense i think , like overall footprint of the mains vs the crosses. longer/dense =shorter/spread out.
