Many players who use the Yonex NANOFLARE 700 PRO say the same thing:

“The racket swings incredibly fast,
but the shuttle doesn’t feel very solid or concentrated.”

In most cases, the problem isn’t the racket.
It’s the string and tension setup.

Understanding the Design of the NANOFLARE 700 PRO

This racket is built around speed and responsiveness.

Head-light balance
→ Fast swing initiation, excellent for defense, drives, and quick interceptions.

Medium to medium-flex shaft
→ Easier power generation, the shuttle can be lifted or cleared without excessive force.

High frame rigidity with strong torsional stability
→ When strung properly, the racket produces a crisp sound and reliable control.

However, if you simply follow the common advice that “speed rackets should use very high tension”, the result can be the opposite of what the frame was designed for.

Players often experience:

• A crisp sound but slow shuttle speed

• Excessive arm fatigue

• Weak smash quality

• 

Three Practical Stringing Approaches

The following setups represent different playing styles.
(The string models are examples rather than strict rules.)

1. Thin Repulsion Strings

Speed + Explosive Feel

Gauge: 0.63–0.66mm

Examples:

• Yonex EXBOLT 63

• Yonex BG66 Ultimax

• Victor VBS-66N

• 
• 

Best for

• Players with fast swing speed

• Those who like intercepting and attacking early

• Doubles players who rely on quick point pressure

Suggested tension

• 4U female players: 22–24 lbs

• Male players: 23–27 lbs

Thin strings help the shuttle leave the string bed faster, complementing the racket’s speed-oriented design.

2. Medium-Firm Control Strings

Backcourt Attack + Drive Pressure

Gauge: ~0.61–0.66mm
Medium-firm hitting feel.

Examples:

• Yonex EXBOLT 65

• Kizuna Z61

• Kizuna Z66 Lusty

Best for

• Doubles players who mix rear-court smashes with fast drive exchanges

• Players who want slightly more control without losing speed

Suggested tension

• Most male players: 24–25 lbs

• Technically stable players: 26–27 lbs

This setup provides a firmer shuttle hold, which improves directional control during fast rallies.

3. Durable & Comfortable Strings

Stability + Arm Protection

Gauge: 0.68–0.70mm

Examples:

• Yonex BG65 Ti

• Kizuna Z69P

• Victor VBS-68P

Best for

• Players who train frequently (3+ sessions per week)

• Those who prefer durability and arm comfort

• Players recovering from elbow or wrist fatigue

Suggested tension

• Female players: 22–23 lbs

• Male players: 23–25 lbs

Thicker strings reduce shock and improve durability while still maintaining a stable hitting feel.

A Quick String Bed Insight

Understanding string bed behavior is crucial:

Hard string + very high tension + insufficient swing speed

→ Dead string bed
→ Shuttle leaves slowly
→ Loud sound but poor shuttle speed

Balanced gauge + appropriate tension

→ Better elasticity
→ Clear shuttle speed
→ Crisp yet controlled feel

Because the NANOFLARE 700 PRO is already a head-light speed racket, extremely high tension can easily make it feel:

“fast to swing, but difficult to generate real shuttle speed.”

What the NANOFLARE 700 PRO Should Actually Feel Like

When the string setup is correct, the racket typically delivers:

• Very fast swing speed

• Excellent defensive response

• Clean shuttle release

• Comfortable overall feel

If your experience is far from this, the first adjustment should usually be string gauge and tension, not the racket itself.

Small changes in these two factors often transform the entire playing feel.
