This another reason why racquets are very much an individual thing - each will function differently in different hands and different styles. The Yonex graphs are there as a comparison for what they are INTENDED to be. When you wield it, it will become what it is to you.

But it shouldn't deviate that far from the intended specs anyway, so the graph is a good rough guide. The most accurate guide will be your own arms.

I smash better on a Ti10 than on my MP100, better speed and height (both stringed with BG68ti at 23 lbs.) and yet the Yonex chart says the MP100 is more powerful.

Anyway, wilfredlgf is right, the chart is just a good rough guide, your performance is a more accurate guide.

The ISO-TI racquet came in 4 versions with different stiffness.
From most flexible to most stiff: SA SR SS SX

Thanks a lot for taking the time to explain what it meant. Nowi finally am able to get it.

Interesting to compare the Japanese ratings to the ratings of the Yonex Thailand site. Notice the position of the NS8000 vs MP100. Maybe TH racquets are indeed different

**dse5001** · 08-30-2005, 09:14 PM

Probably "Matrix-007" for the next one.

**jerby** · 10-08-2005, 05:56 AM

ok, the vertical ranking is explainable..offensive or not.

but what's teh deal with singles/doubles? control? durability?

I just noticed this. Hmmmmmm, I'd say more marketing than real world experience because though the NS8000 is powerful for it's relative lightness, it's definitely not the most powerful racket in the Yonex line-up. In fact, I feel the Ti10, MP100, MP99, AT700, AT800-OF, AT800-DE and Cab30 are all more powerful. I haven't tried the others or not enough to make a fair comparison. YMMV.

??

look at the MP40/44, i dont understand how in one it can be above the Y-axis line, noticably above the MP80/88 and in the other below the 60/66 which is noticably lower than the MP80/88

so what is it exactly? ><

**Stijn** · 10-08-2005, 12:36 PM

When the NS8000 came out, the position of the NS7000 was changed to more defensive.. I guess it's a way of marketing...

Japanes Muscle Power 40 is a different racket to UK MP44

oh ok thanks.

Stijn,

doesnt look like the NS7000 was moved at all with the addition of the NS8000?

In this chart, no, but I've seen (possibly Belgian) charts with the NS7000 at top.

Kind regards,
Stijn

In different parts of the world there are different specs to the models. Not versions as some of you believe but specs. For instance in Canada there are specific grip sizes and weights offered that the chart is based on for Canada and the USA. In other areas the grips and weights are different to reflect the differences in buying patterns of each area. North Americans for the most part want raquets with larger grips and weights than Europe and Asia. The charts get printed for each territory by the distributor not by Japan. Because some of the raquets only come one way in a territory they are different than Japan. Example MP88 for Canada is one grip size/one weight. Not so in other parts of the world. Same as the MP44 in Canada is different for Canada and Great Britain. As for doubles and singles differentiation the chart is a rough guide as this is what the raquet is intended for by the design team not a law. Still the bottom line is try before you buy.

SA = less stiff + head light

Kwun, I think most people here, including myself, are confused by the actual criteria Yonex take to decide where to fit a racket into the chart. your explaination is by far the clearest. May I rephrase it this way without changing any meaning of it:

more shaft stiffness = offensive play-oriented
less shaft stiffness = defensive play-oriented

reason being stiff shaft helps you smash harder;

more head weight = singles play-oriented
less head weight = doubles play-oriented

reason being less head weight helps quicker game play pace.

However, I do have a few questions. First off, there are more factors of a racket than shaft stiffness and head weight that need to be taken into consideration, it is to me too arbitrary, therefore unlikely close to truth, to use merely two factors to draw this graph. Yonex purposedly make the criteria vague though.

Secondly, does a stiff, or extra stiff shaft the only thing that helps you smash harder? Don't we remember what a heavy head (apart from NS series) can do for your smash has been massively discussed and believed in the forum?

So the simple question is, what parameters on earth are the X axis and the Y axis actually based on, I mean, in technical terms, no as vague as singles or offensive oriented. Let's get right to the core. I looked through 7 pages of discussion in this thread and found that this question hasn't had a clear answer yet. (Am I missing anything here?)

Thanks for reading.

Well, it isn't very simple to make a chart I guess. Different players prefer different rackets. However, to help the customer somehow, apparently Yonex developed this chart to give you a direction. If you already know what kind of racket (stiff, head-heavy,...) you want, the chart can be quite useless and confusing.

totally agree.

i seem to remember somebody saying that the chart wasn't based on racquets at all, more a survey of people who use yones racquets and what type of players they thought themselves to be..

this said the charts are useless..unless you value the opinion of other people..

The question of most importance here is not about the usefulness of the chart, but about the criteria yonex use to fit every racquet into it. i.e. WHAT ON EAHTH the x-axis and y-axis are based on.

Besides, I don't think one can accurately evaluate the usefulness or uselessness of a chart before one can interpret it.

Where a racquet fits in the chart being based on the way professionals use it is definitely purely fictional.

First off, some racquets in the chart are NEVER used by any professionals.

Second off, if it's based on players, not racquet itself, why does AT700 have such an EXTREM attack to defense ratio in the chart? Is it because its users, such as Taufik or Chen Hong or Peter Gade, by nature are so much an attacker and so little a defender? Or is it because pros play so much attacking and so little defending with AT700, statistically? NEITHER.

Third off, if it's statistics, why does AT700 have such a MODERATE singles to doubles ratio in the chart? AT700 is vastly used by singles players (there are a few who use AT700 in doubles though), but AT700 is, so are many other so called "singles rackets", IN THE MIDDLE of x-axis. That suggests equal number of singles and doubles players who use AT700. Something doesn't sound right here, right?

The belief that the chart is statistics is to me fallacious.
