How do you find a location of a Center of Percussion?The Head Youtek Graphene Speed S seems to fit to your desires perfectly: 100 sq in, 22mm beam, 285g (unstrung) It has a high value of Center of Percussion (what you are looking for).
Do you mean high, as in towards the tip, or high towards 3/9 o' clock when the racquet is horizontal, like when hitting forehands?
In my experience, a racquet with an upside-down teardrop sort of head shape can be very good for catching the ball up toward the top of the string bed. No matter what the head shape though, I'd expect a string bed to respond better in just about any racquet if it had some weight added up at 12 o'clock.
A Yonex may also be good, but I've found that compared with a more oval shaped hoop, the somewhat squared off top of a typical Yonex can make for a sweet-spot that ends rather abruptly up toward the 12 o'clock end of the strings. The ones I've owned have seemed to have inherently wider sweet-spots, but didn't seem to have a gradual fall off up toward the top. Just my take on those - the proof is in the demos!
Used and still own a Head iTour with an inverted teardrop shaped head.
You can locate it mathematically. However, you don't want to. It was once believed that the center of percussion was very important in play. This belief had very solid theoretical underpinnings. But experiments later showed that as soon as you add the weight of the hand to the racquet the COP moves into the throat of the racquet and so is irrelevant in play (unless you customarily throw the racquet into the ball, or hit the ball with the racquet's throat).How do you find a location of a Center of Percussion?
I hit the balls about 2 cm above the middle (3/9 o' clock) when the racket is horizontal.
I can see it on the strings.
I've enjoyed this shape myself with the old Prince NXG mid. If memory serves, I think the iPrestige mid had this hoop shape, too.
The formula is: COP = SW / (m · r) , whereHow do you find a location of a Center of Percussion?
Isn't OP asking about higher towards 3, 9 vs 6, 12?

I'm interested to hear the responses for this. Wouldn't this contact point be ok if you are hitting topspin?
Is the correct spot to hit a ball in the middle of the stringbed?
Wishes:
- power
- control
- max. 100 inch
- small beam (about 20 mm)
What about the O3 rackets?
When you say string the last 3 crosses at a lowr tension, you mean with the same piece of a string?
Can you mention rackets?

YES!
everyone seems to be ignoring what he is saying and just assuming he means high towards the tio. That's why I asked him to clarify.
Sorry, I meant this one:

There's also a 18x20 and a lighter Team version.

Probably 'tip'
I have found the following to be generally be true: Dunlop and Head have sweetspots lower in the stringbed. Wilson and Babolat have sweetspots higher in the head. There are some deviations from this, however.
Best racquets for hitting high in the stringbed:
1) Wilson Blade 98 and Blade 93
2) Babolat Aeropro Drive (GT is slightly better for this than newer version).
3) Babolat Pure Drive, Pure Drive Roddick, Pure Drive +, Pure Drive Roddick +. Pure Drive Roddick + is best for this.
4) Prince Exo3 Tour 16X18, Prince Exo3 Tour 18X20. 16X18 is slightly better for this.
5) Wilson Juice 100L.
I hope that helps.
What do you mean 'tio'?
Based on your criteria, I think you will have to make some compromises. The Prince Tour frames are great, but they definitely lack serving power-- otherwise, they meet all of your other criteria. The Blade 98 (either 16X19 or 18X20) also meet your criteria-- except for sw. If you purchase from TW, they can sort and find lowest sw within the factory tolerance.
You may also want to look at the Slazenger 98 Tour. It's supposed to play very similar to the Blade 98 and the power map indicates that it should be good for hitting higher in the head. The upside is that it's only $49!
now playing with the bb London with some lead on 10/2 and 6 and I want som more service and groudstroke power.
