For comparison, I made of list of player rackets with power ratings obtained from TW's official reviews and made categories to see how the rackets compared with each other. Here goes:

Lowest power rating category: 58-64

Wilson ProStaff 6.0 85 - 58
Yonex RDTi 88 - 61 (actually I feel the power is less than 6.0, more like 57)
Head IPrestige Mid - 62
Wilson NCode 90 - 64
Yonex RDX500 midsize - 64

Low-medium power rating category: 65-70

Wilson Prostaff 6.0 95 - 66
Head IPrestige Midplus - 66
Dunlop 300g - 68
Dunlop 200g - 68 (interesting, same as 300g)
Yonex MP Tour 1 90 - 68
Prince Diablo Midplus - 69
Yonex RDX500 midplus - 70

Medium power rating category: 70+

Yonex MP Tour 98 - 71
Diablo Tour Midsize - 71 (surprise entry for 93sq.in. midsize)
Head LM Prestige Midsize - 71 (power due more to mass than inherent power)
Head LM Prestige Midplus - 75

Of the rackets I own on this list, I agree with the power rating (exception being the Ti70 88 which I felt was lower !). For me, the only real surprises were the high power level of the Diablo Mid and Head LM Prestige Midplus.

I had an idea of listing these same rackets in categories of control and see the inverse relationship between power and control. Maybe there's a couple of rackets which scored higher in both categories ??

Notice that the Diablo Tour midsize is more powerful than the midplus (!) which isn't surprising considering how light the midplus is.

Here are the same rackets but the scores next to them show *control* instead of power, obtained from TW's reviews.

Lowest power rating category: 58-64

Wilson ProStaff 6.0 85 - 90
Yonex RDTi 88 - 78 (I feel this is alot higher, at least 90 !)
Head IPrestige Mid - 84 (I agree, pinpoint control)
Wilson NCode 90 - 78 (this is lower than I would have imagined)
Yonex RDX500 midsize - 81 (about right)

Low-medium power rating category: 65-70

Wilson Prostaff 6.0 95 - 80
Head IPrestige Midplus - 81
Dunlop 300g - 74
Dunlop 200g - 71 (this seems way odd considering 18x20 and lower than 300g ?)
Yonex MP Tour 1 90 - 81
Prince Diablo Midplus - 82
Yonex RDX500 midplus - 78

Medium power rating category: 70+

Yonex MP Tour 98 - 81 (this looks umm....on the high side ?)
Diablo Tour Midsize - 84 (Diablo = IPrestige Mid in control, don't think so)
Head LM Prestige Midsize - 82
Head LM Prestige Midplus - 80

So there were some unexpectedly low entries (ncode 90, Ti88, 200g) and definitely some higher ones than expected (Diablo Tour, LM Prestige series !). Based on the combination of power/control, we should all be using Diablos and Head LM Prestiges. Negative.

My primary and backup rackets, RDXmid and IPrestige mid, while low powered, scored above 80. In general, though, the player rackets all did very well in terms of control

ferrari, thanks for making a good data set.

I did some statistical analysis and found that there is no meaningful relationship between power and control; power and control are neither mutually exclusive nor incompatible. Power racquets can be control racquets at the same time, and vice versa.

Caution: The number of cases (only 16 here) for my statistical analysis is meager.
However, even with that proviso, the negative relationship is not
strong. (Pearson correlation coefficient = -.30)


Correlations
POWER CONTROL
POWER Pearson Correlation 1.000 -.299
Sig. (2-tailed) . .260
N 16 16
CONTROL Pearson Correlation -.299 1.000
Sig. (2-tailed) .260 .
N 16 16

This is really surprising to me, I would have thought a very linear inverse relationship between power and control !!
