Safe string tension

1) WOW, you have an agent? What kind? Movie? Just kidding...
2) Is it new when you bought it? If so, I assume you did not request "proportional tensioning" method. If so 90% chance it was not done in that method because not too many stringers will use that method unless it is specifically requested. Not many know how to do it correct too.
3) "Safe" is a relative term. Just like s e x, if you don't know who you are dealing with, it is better to stay away and be safe. Just another bad joke. But in all serious term, there is a recommended tension on the racquet cone. It is 19~24lb. So you prob want to stay in that range in case the racquet has a defect and you need a warranty replacement.
4) What other member here use as a rule of thumb is 2lb or 10% rule. You can do a search on that topic. Anyway. it is for example, you string mains at 22lb and crosses at 24lb. Or 10% higher on the cross.
5) If you are happy with NBG95, stay with it. People use different string for different reason. I like BG85 because it is thin and rough. While other likes BG80 for better smashing sound. Some other say BG68ti is great for smashing power. Other use BG65 because it is cheaper and durable. You need to pick one that is best for all your needs.

 

1) Sorry to hear your AT700ltd loss. In fairness, AT700s is less likely to survive a clash with AT900-p
2) So if the stringer is know to break 2 perfectly good racquet at 30 lb. Why are you still going back to him? I have done NS9900 at 33 lb and other Yonex at 27 and 28 lb and they have been fine.
3) The truth is, it is all in the stringing person's experience and skill. How much he know the machine to compansate.
4) Can you find another stringer in your area?

 

Be respect to others, when you clearly do not know his work.

Pre-wave is very common in stringing, it will not cause any damage, under the assumption the stringer is doing the right thing. Whether he tension the string on the same day, or 2nd day, or 3 months later, it does not matter, as long as when he started to tension, he finish all the pieces not leave half tensioned and half not on the 2nd day.

Please learn and be sure, before accuse others.

 

1. So, seems you two clashed when he was hiting forehand (assume he is right handed), and you were hitting backhanded? Unless he is way into your part of coverage, otherwise, it's usually YOUR fault for the clash. Because in double, if the shot is in the middle, the person with the forehand stroke usually should take the shot, instead of the one with backhand.

2. Clash is never a good indicator about racket's durability or string job quality. If you swing hard, a tennis racket can broke during clash, never to mention badminton racket. You tension can be 15 lb, but if clashed at the wrong spot, it can be gone.

Reading your later posts, I still have a hard time to see why you can use rather biased reasons to accuse the stringer. Of course, I do not know the stringer in person, and maybe he did contribute some fault from his part. However, with your "reasons", I start to think more and more, as it's purely "finger pointing", as you does not know what you are doing, as well.

 

I rarely see rackets with frames broken due to high tension. I do see it, but those are usually very advanced players with definitely over 25lbs tension. I play at about 25lbs crank or 22lbs on a constant pull. I'm pretty emotional when I play much like Roddick in tennis and i get in a good racket toss every now and then, and I still dont break my racket on the ground.

I also dont see a lot of rackets that break due to clashes. I see a lot of clashes, and a lot of paint chips, but usually not a straight clash -> break.

I think your main concern if you string at high (or low) tension is avoiding clashes. In a clash, all bets are off. Im pretty sure even Dink's Ultra will break in clash that would break a ns9900. Dont blame the stringer or string tension in a clash. If your frame is damaged you wont be getting any sort of warranty, but if your frame is clean you could still claim warranty. Lastly, if you want a guaranteed safe range, there is a sticker on your racket that says what its warranted up to. Use that as reference.

 

1. So, you mean you are on the left side, and trying to hit a backhand? Or, you are on the right side of court, to attempt a backhand. If on the right hand side, it's still your partner's shot, instead of yours, assume both have reasonable coverage of the court. Anyway, this is not the key point of the discussion.

2. Whether it's the weak spot, or strong spot, a clash is a clash. I saw tennis racket broke at the throat / handle during a clash in a tennis double game. Clearly, tennis rackets are much stronger than badminton ones. Therefore, relatively strong or weaker spot, nothing is bullet proof in clash.

3. Do a search regarding the "skip cross". It's been discussed numerous times, as it will not really affect anything, regardless playability or durability. Team up with the fact you even question about "pre-weaving", I have to conclude that you seem do not know too much about string racket, and tend to finger pointing to the stringer.

My point of all these replies, simply saying the major factor for your racket's breakage is the clash. Whether the tenison is high or the stringer's skill, might be very minor compare to the clash. You can have an empty frame with no string at all, it can be broken when you clash or hit the wall something.

 

Blizzards, out of interest, where in Brunei did you get your racquet strung? Was it in Kiulap by any chance? Just curious as I bought an AT700LTD there and they did a rubbish string job - so bad that I cut the strings as soon as I got the racquet home.

 

^ safe tension?

all yonex higher models can withstand 30lbs. its important to know how to take care of your rackets. if you clash with 18lbs strings you can still break the racket.

i would recommend to get your own machine, it'll be more economic in the long run.

 

kind of off topic here but isn't it a big switch to go from a at700 (the most head heavy yonex racquet) to a ns9900 which is head light ?

Safe stringing tension ?

Probaly 19-25 would be safe as enything more than that would probaly mean that a clash or mishit would result in breakage after one or two occasions

 

While, it appears that you still did not get my point at all.

Any well built all graphite rackets (be it Yonex or other reputable manufactures) can take tension of 25 or even 30lbs easily. However, that does not mean 20lbs can take 5 clashes, 25 can take 3, and 30lbs can only take 1. If the clash is hard enough, you can have a racket frame (w/o any string) to break. My point is, your breakage is due to the clash mostly, and 25lbs is quite safe for today's rackets.

Anyway, you did intentional did the finger pointing at the stringer, when you even did not know the "pre-weave" of stringing, and accuse he is a "moron", when his method clearly did NOT have any negative impact on your racket, from what I read in your earlier post.

 

I assume the Cab15 is 2U, which by design, it suppose to be more durable than 3U or 4U to begin with. Also, cab series might be the most durable series in Yonex modern ranges, due to it's frame design.
