While the string pattern of the other Pure Aero racquets in the range is 16 x 19 (16 main, 19 cross), the PURE AERO 98 racquet features a tighter string pattern (16 x 20), offering a little more control while maintaining excellent spin.

21/23/22 beam The combination of a 98 in² head, a thin 21/23/22 beam, and a 16/20 string pattern brings control and precision to the spin-friendly Pure Aero family.

The frame offers a confidence to go after the ball without a fear of overhitting that wasn't quite there with the previous VS, and certainly not so from the standard Pure Aero. It's also perhaps the most comfortable, arm-friendly Aero.

The Babolat Pure Aero 100 was also a significant step in the right direction this year, thanks to the denser string pattern. The 98 offers better control and is faster through the air. But it's not quite as forgiving and powerful as the 100.

Beam Width: Most control racquets have beams between 18 and 21mm with most power rackets having beam widths of 25 to 28mm. Racquets with beam widths between 22 and 24mm provide a mixture of power and control.

Beam angle of a light indicates the spread of light from the light source. The beam range is usually between 15° to 120°. A narrow beam is between 15° to 45° and a wide beam is between 60° to 120°.

Yonex Ezone 2022 98 vs 100 The 98 is faster through the air thanks to the smaller head size and thinner beam profile, while the 100 is more powerful, more forgiving (easier to use) and a bit more spin-friendly. Basically, with a bigger head size of the same racquet model, you pretty much get more of everything.

I-beams have a much more narrow flange in comparison to their web. Key characteristics of wide flange beams include: They are much heavier than I-beams, meaning they can typically take more force. They have a thicker center web, often increasing their strength.

In other words, Beam width is the area where most of the power is radiated, which is the peak power. Half power beam width is the angle in which relative power is more than 50% of the peak power, in the effective radiated field of the antenna.

For a standard ceiling height of 2.4m to 2.7m, a wide beam angle of 60 degrees or more is recommended. Whereas, for higher ceilings, a narrow beam is a better option and you'll need more lights to fill the space.

Overlapped beam angles ensure that light covers all your space (preventing accidents). The standard height of a ceiling is roughly 7.9 to 8.9 feet where a wider beam angle, 60 degrees or more is sufficient. If your ceiling height is more than 8.9 feet, you will need a narrow beam angle of 45 degrees or less.
