forgive me if these topics have already been raised but i tried searching and didn't find anything: 1) is it true that 2 knot stringing is not suitable for an isometric frame? 2) the green dot on yonex rackets sold in m'sia/s'pore/indo, the one which says pbsi, do they break more easily since they are 'only' made under license? thanks for your help guys.
1) it's better to have more knots because you save on stringing in that if a string break, you can just restring the broken part. Works well with all racquets of all shapes and sizes. A pack of 10m string will last you a long time after the initial stringing. 2) The green dot tells you the quality of the racquets similar to the color dots of nylon shuttles. Red - no good, Blue - better, Green - best. Some of us actually believe that there are gold and silver dots which are reserved for selected countries like China and Japan. In case you newer posters don't get it. I am just kidding. I don't mind answering questions (even if repeated questions) but please use a little bit of common sense.
first is the country codes, ..... now is the green dots .... here is my reply: I emailed yonex japan again and again ... and finally the person in charge for sales in Asia countries replied ... and someone from yonex singapore & malaysia called me as well. Re: Re_[YONEX Inquiry: No.3446(2003-05-15)] Sent: 6/2/03 10:29 AM Importance: Normal Dear sir, Thank you very much for contact us again. I am Satoshi Yuza who is in charge of sales for Asian countries. As our staff had informed, all the rackets we sell all over the world has the same quality. "JP" means one for sale in Japan, "TH" means one for sale in Thailand. But they are exactly the same quality. You think rackets marked "TH" are weak. But it may be the reason you accidentally see their breakage at your side often. Actually I collect claims of breakage from all agencies in Asia. Then I always find that the percentages of breakage are almost the same among each country. The stringers at your side are exactly wrong. As I said, rackets marked "JP" and others are exactly the same quality. They just think that "JP is for Japan, so better quality and stronger." You will see, if we produce rackets which is different quality for each countries, our factory have to produce them by each different way. Producing several kinds of quality makes us spend more time than producing one quality. This costs lots more to us. We never put different quality on one item. Thank you very much for kind attention to us. I hope this will be help for you to understand us. If you still have some question, please feel free to contact me. Thank you very much and best regards, for those who still believe that there are different qualities, you can start engaging your lawyer now.
Basic on personal experience, I think 4-knot string method seems fit for ISO rackets better: 1. Seems 2 separated strings could better maintain balance for ISO 2. For a using of "weight drop" machine, 4-knots seems much easier.
thanks all of you for your replies. i feel a little bit more confident in my mp77 with that green dot now! as for the stringing, i'm still learning how to string my own racket so i'll take your word for it that 4 knot is better than 2 knot. thanks again
1) For me 4-knots is better than 2-knots. 4-knots means that you use 2 pieces of string, 1 for main and 1 for cross. 2-knots means 1 string. if you use 2 strings (4 knots), main and cross string will not take effect to each other. Since cross get more tension than main. But if you use 1 sting, main and cross will take effect to each othes. Days by days the tension will be "adjusted" to be equal. Correct me if I am wrong !!! 2) Sorry I don't know what it means. Can you people tell me where to find this kind of DOT ?
Actually, to me, the main advantage for 4-knots over 2-knots besides "ISO shape issue" are: 1. Easier to adjust different tension for main vs cross (especially 2 point support machine) 2. Easier to deal with the massive length of string (about 16, 17 ft instead of 33 ft or even a big reel)
Bringing up an old thread and my worthless 2 cents worth compared to all the experts here: A clash happened between my friends 6 month old MP77 strung with 2 knots, tied at about the same tension as mine which should be about 24 ~ 25lbs; with a Carbonex 25 which is perhaps 8 - 10 years old with all sort of paint and body chips, strung also with 2 knots. Guest which one broke. The MP77. The Cab 25 don't seem to be even a little shaken or scarred with new 'injuries'. Perhaps this concludes one thing as well : ISO heads, due to the angular shape at the 2 and 10 O'clok positions brings about more stress to the racquet when strung at high tension with single pass (two knots). True? I don't know. You tell me. So far, my Ti-10, victim of such clashes with the notorious Cab 25, touchwood touchwood, had not been harmed, not even a paint chip while strung with four knots, or double pass.
Yeah! Touch Wood! Did you observe, the black paint on the head of the Ti-10 is a matte finish. Less prone to chipping I feel. Hope they are really strong and not covering up whats beneath.
Yeah I notice that too, the Ti-10 top is kinda rough, matte finish like you said and it is very resistant to chipping. Have you ever tried to lick it? The top part taste like rusted metal.
