Hi

String tension is a relative thing. There is no absolute answer. The variables are listed as follow:

1. Temperature
2. Atomspheric pressure
3. Humidity
4. Thickness of the string
5. Strength/power of the player

The general rule is that the higher the tension, the better the control but lesser the power/rebounce.

The higher the local temperature and humidity, the higher the tension. This has an effect on the elasticity of the string.

For example, in Hong Kong, string tension of #24-28 is considered normal. In Canada, it is normal to string to #22 in summer and #18 in winter. In Sweden, it is usually strung to #15-#16 in winter.

For the same reason, faster/lighter shuttles graded #6 or 80 are intended for average local temperature of 10C (range 7-13C), whereas slower shuttles of grade #2 or 76 are for average local temperature of 30C (range 27-33C). In between, #3 or 77 are for 25C(range 22-28C); #4 or 78 are 20C (range 17-23C); and #5 or 79 are for 15C (range 12-18C). This is because shuttles travel slower in colder air (densed air) and much faster in hotter air.

The thickness of the string affect the "true" tension as well. The thinner string of 0.66mm (e.g. Gosen: Alan & Susi) stung at #22 will have the same effect as a 0.70mm (e.g. gosen 70 Pro) stung at #24-26. However, the 0.70mm can go up to as high as #33 and is more durable.

Racquet tension is usually kept as secret amongst the top tournament players. They will bring with them their personal stringers in major tournaments.

Thanks

I tend to disagree with a lot of people on that, when they refer to high string tensions as less power. I feel that the high tension means less of a trampoline effect, where the mass of the shuttle can make it bounce off with a lot of force. The normally means more "control", as in the variable bounce of the shuttle is less existant, and one finds it easier to control the bird with their own power, instead of letting the bouncing bird control itself.

As well, with the absence of a trampoline effect, generating power is harder, because of less bounce. However, if enough swing force is provided to allow the strings to flex, the high potential energy in the strings, should cause power to increase. Except, if you cannot cause the string to bend, it will seem like there is no power in the racquet because there is no trampoline effect to aid in power generation.

bg-66 sharp, more sharp feel, a little bit better repulsion, but considering the price, then i still choose bg-66, except money doesn't matter for you

But unfotunately In Indonesia , a lot of badminton shop doesn't have , correct or calibrated string machine.

Its difficult to choose a correct tension , if you stringing in differen shop or different machine .

25 lbs in one machine is not 25 lbs in another machine....

Found 24X26 lbs NBG98 is my ideal tension and string right now and considering to up to 25X27lbs......

@romizone
Dont forget stringer in here always suggest to high tension like 28-30 lbs to every people asking about ideal tension no matter they are newbie or master in this sport......so not only the machine must be calibrate but the stringer also

BG68Ti 24.5
NBG95 25

That's my best option so far, but I'm thinking to retry, since I'm not sure about that option and I'm not going to cut them T_T... They're pretty "spicy" for my pocket lol xD...

Perfect exemple of why having a good string is better then having a great highend new expensive racket with bad strings (BG 68ti is bad in power compard to BG66)

A good string for the At700 if you want RIDICULES power would be the NBG98 but your string control is going to suffer... Alot. The BG 66 Has good control aswell a great power but durability wise, not so good. Shouldn't be a prob for you since you already have the BG 66 on the At250 so you don't care as much for durability?

But if you want a good all around string, i personnaly prefer BG80 (Like many other players) As good durability, great power (not as much as the BG66 but great none of the less) and good control.

Just my recommendation

I have a question.
Most players here use about 17 lbs (8 kg) of tension. Mostly they use BG80, BG95, BG65 and Flex 21.
What I read here, is that a lot of you use 22 lbs (10 kg) or more. So what's up with that? Are you all pro's, or am I missing something?

17 lbs? That is extremely weird.

Most people I know string their rackets between 23 - 28 lbs.

Yes, I know it is weird.
I'm probably mistaking, but I'm trying to find out where...
Lbs is pounds, right?
I use the Google-convertor for lbs/kg-calculations.
I really don't understand it, but I'm going to ask it in the shop again.

I use 3 of Original Armotec 900 Power with different type of sting and tension with using Digital Electric Yonex Stinging Machine (ES5PRO):

BG-80 @ 32lbs, Smash rating: 9 of 10; Control rating: 5 of 10
BG-80 @ 29lbs, Smash rating: 8.5 of 10; Control rating: 7 of 10
BG-85 @ 28lbs, Smash rating: 7 of 10; Control rating: 9 of 10

If your wrist is not strong, dont try this at home. Your wrist or arm will be pain..

Just to check, if my girlfriend is a beginner, not much strength as well, what's the best string tension for her? Btw, thinking of buying a flex or medium flex racket for her, which better suits her?

As for myself, I am not the strongest guy but still packs a punch, so what's the best tension and flex for me?

Chances are, she'll want a flexible racket strung at a low tension. (20Lbs maybe slightly higher or lower - play around with it a bit)

For you, I'd go for a medium-stiff racket strung at a medium tension (24Lbs or so)

Noted, will consider about it (actually, after reading all the forums, that's more or less what I'm thinking of doing).

Thanks again....
