Guys,

I took the Racquet Selection guides for years 2004 through 2006 and combined them into an Excel file that allows you to sort them by your selected criteria. Most of the information came from the Racquet Selection Guide: http://www.racquetsportsindustry.com/issues/200602/200602racquets_outlook.html

I added a "Quality Index" column using the formula from Racquet Research ( http://www.racquetresearch.com/ ) to further help in racquet selection.

The 2005 racquets are in black, 2004 in blue, and the 2006 models are in red. You can download the spreadsheet here: http://h1.ripway.com/ar1506/rackets2004-2006.xls

Feel free to make modifications or improvements and repost for everyone to use. Let me know your thoughts. Is this helpful?

Exceptionally helpful. Great job.

Would suggest changing the formula for grams to ounces conversion, though. You have .04 in there right now, and its actually .035274. For us non-metric types, this makes a difference.

you might want to plug in the 2004 data too for completeness sake's.

they are avaiable in my posting in the Comparison Sticky ... or here:

Just to add, this is how you can calculate that Power level number in column L.

Power =(Length Index * Head size * RDC flex rating * swingweight) / 1000

where,

Length index is computed by 1 + ((Length in inches - 27) / 10)

The flex ratings for a couple rackets that I'm interested in are a couple points higher than those given on the TW site.

Volk Tour 10 V-engine MP - 65 vs 62,
Prince NXGraphite MP - 66 vs 63

Are they measured the same way? Which do I believe?

Wonderful data.

I did not find Flexpoint Radical Tour. Can you add that?

Thanks.

TW and ******* Sports use different ratings for flex ratings. Which one is best I do not know.

Isnt the formula Power = Head size * Flex rating * Swingweight / 1000 because if you do it with the length index the number becomes really high......
For example Ncode tour 90 : 90 * 66 * 326 / 1000 = 1936

If you do it including Length index then its 27 * 90 * 66 * 326 /1000 = 52283....... that cant be right

I sent it to you via email.

Apparently, the site hosting the file for me has a bandwidth limit. So many people have downloaded the file, the daily bandwidth has been exceeded. It should be available again tomorrow at the latest.

Thanks a lot AR15.

According to me there are some mistakes from Racquet Selection Guide :

Lets take the Aerotour they said SwingWeight is 300 it looks impossible ...

And TW doesn't find the same Sw for this racquet !

AR15

I'm not sure where they got their data on flex or swingweight. Maybe someone else knows.

Probably, the important thing when comparing racquets is to have the measurment type consistent for all makes.

Edouard

Agree ...

The same for Balance Point

For the Pure drive Tw says 33cm strung
Racquet sport Industry 33.5cm ...

Nice job. In a similar vein, this is the input for the relative racket finder:

http://specgeek.50megs.com/rackets.txt

You might first need to go to: http://specgeek.50megs.com

...then click on "rackets.txt"

What is the "points" column? And are there TW values (like comfort, overall) for the rest of the racquets somewhere?

Points head heavy or head light. Comfort, etc. comes from rackets reviewed by tennis warehouse.

Do you think it is possible to make a "control indicator" with these specifications ?

Well Racquet sport industry gives a formula that rates power of racquets :
Formula = (length index headsize flex swingweight) / 1000

I would like to find a formula that rates the level of Control or shots Accuracy of racquets.

Yes, that would be interesting. But, wouldn't using the power rating in reverse, do the same thing? In other words, racquets with the least power, most control?

So, if you were looking for a control racket, but wanted it "arm friendly", perhaps you could sort by "power" ascending and "quality index" ascending.

Well i don't think control is the opposite of power.
Because that would mean that wilson nfury (100sq even balance low flex) is the best control oriented racquet available ! even Better than Sampras Sticks !

Sure no racquets can have excellent control and excellent power.

Cool, nice work! Just a suggestion for the next time: might want to think about including the string pattern for the racquets.
