Volkl Psycho Hybrid is a packaged polyester-and-multifilament tennis string set that combines Volkl Cyclone with Power Fiber II. It is designed for players who want shaped-polyester spin and control with more power, comfort and touch than a full bed of Cyclone.

Cyclone is a ten-sided co-polyester monofilament. Power Fiber II is a soft multifilament with a gut-like response. The two strings can be installed in either orientation, allowing the player to decide whether spin and control or comfort and power should dominate.

Psycho is best suited to intermediate and advanced players who have the technique for polyester but want a more forgiving stringbed. The Tennis String Finder can help compare the hybrid with complete multifilament and co-polyester setups.

Volkl Psycho Hybrid Rating

The two components are different materials, so the package’s gauge label should not be interpreted as proof that every strand has an identical diameter.

Material and Construction

Psycho is not one blended string. It contains two separate half sets that create a hybrid after installation.

Cyclone is a solid co-polyester with ten sides. Its geometric profile adds ball bite and helps advanced players control fast swings through spin.

Power Fiber II is a flexible multifilament designed to reduce impact harshness and add power, touch and pocketing. It is physically softer and more vulnerable to abrasion than Cyclone.

The main strings dominate the response. Cyclone mains create a polyester-led setup, while Power Fiber II mains produce a softer, livelier hybrid. That orientation should always be stated when comparing performance.

Volkl Psycho Hybrid Performance

Power

Psycho offers more power than a full bed of Cyclone. The multifilament component stretches more readily and adds useful depth on serves, defensive shots and moderate swings.

With Cyclone in the mains, power remains controlled and suitable for fast strokes. Power Fiber II mains create a noticeably livelier launch.

Independent testing of the poly-mains arrangement found a balanced level of pace rather than an uncontrollable trampoline response.

Power rating: 7.5/10

Spin

Spin is strong, especially with Cyclone in the mains. Its ten-sided profile grips the ball, while the softer cross allows useful pocketing.

Independent testing found less bite and snapback than a complete Cyclone bed because the multifilament cross can notch and restrict movement. The hybrid still scored above average for rotation.

Power Fiber II mains shift the balance toward comfort and reduce Cyclone’s direct influence on ball contact.

Spin rating: 7.5/10

Control

Psycho provides excellent control in the Cyclone-mains orientation. The polyester limits launch, while the multifilament adds touch on volleys, slices and shorter strokes.

The setup is easier to drive through the court than full Cyclone without becoming excessively unpredictable. This makes it useful for all-court players rather than only heavy topspin baseliners.

Control becomes livelier with Power Fiber II mains and can decline as the soft string frays or the intersections lock.

Control rating: 8.5/10

Comfort and Feel

Comfort is a major advantage over a complete polyester bed. Power Fiber II adds cushioning and ball pocketing, reducing the rigid impact associated with full Cyclone.

Independent playtesters also praised touch and connection across volleys and finesse shots. Cyclone mains retain a crisp foundation, while Power Fiber II mains produce the softest arrangement.

The poly-mains version is still polyester-led. Players with active arm pain should not assume that one soft component makes it equivalent to a complete multifilament setup.

Comfort rating: 8.5/10

Durability and Tension Maintenance

The Cyclone strand has strong physical resistance. Power Fiber II is normally the limiting component because it can fray, notch and eventually break against the shaped polyester.

Independent testing found good overall playability duration, but also visible shredding of the soft string. Spin can decline before breakage when the intersections restrict main-string movement.

Useful life depends on orientation. Cyclone mains often saw through the crosses, while Power Fiber II mains expose more soft material directly to ball impact.

Choosing the Right Gauge

PackageGeneral characteristics
16-gauge combinationGreater stability, control and resistance to breakage
17-gauge combinationMore pocketing, power and spin with faster soft-string wear

The 16-gauge package is the safer starting point for open patterns and regular string breakers. The 17-gauge package suits denser patterns and players prioritizing response.

Full Bed or Hybrid Setup

Cyclone Mains With Power Fiber II Crosses

This is the control-oriented arrangement. Cyclone dominates spin, launch and physical resistance, while Power Fiber II adds comfort and touch.

It is the most logical setup for established polyester players seeking a softer response.

Power Fiber II Mains With Cyclone Crosses

This orientation emphasizes power, pocketing and comfort. Cyclone crosses lower the launch and add firmness.

The shaped crosses can notch the multifilament mains quickly and may restrict their movement.

Using the Components in Full Beds

Both strings are also sold separately. A full bed of Volkl Cyclone maximizes polyester spin and control, while a full bed of Volkl Power Fiber II maximizes comfort and power.

General Tension Guidance

The two materials do not need identical tension. The polyester component is commonly installed lower than the multifilament because it is firmer and less elastic.

Large differentials can distort the intended response, so adjustments should remain conservative. The main-string material, racket pattern and previous setup matter more than one universal number.

Stay within the racket manufacturer’s range. The Tennis String Tension Calculator provides general guidance, but hybrid judgment may require an experienced stringer.

Who Should Use Volkl Psycho Hybrid?

Psycho is best suited to:

  • Intermediate and advanced players
  • Polyester users seeking more comfort and power
  • All-court players who value touch
  • Players wanting a ready-matched hybrid package
  • Healthy topspin players needing a less rigid setup
  • Users willing to monitor multifilament wear

Who Should Avoid Volkl Psycho Hybrid?

Psycho is less suitable for:

  • Beginners who do not need polyester
  • Players with current arm discomfort seeking maximum softness
  • Frequent breakers wanting a full polyester bed
  • Users who dislike changing hybrid performance over time
  • Players wanting maximum shaped-poly snapback
  • Buyers seeking the simplest possible setup

Volkl Psycho Hybrid Compared With Other Strings

Psycho vs Full-Bed Volkl Cyclone

Volkl Cyclone in a full bed provides stronger spin and physical durability. Psycho adds power, touch and comfort through Power Fiber II.

Psycho vs Volkl V-Fuse

Volkl V-Fuse pairs Cyclone with natural gut rather than multifilament. V-Fuse offers greater elasticity and tension stability at a higher price.

Psycho vs Wilson Champion’s Choice

Wilson Champion’s Choice combines premium natural gut with ALU Power Rough. Psycho is less expensive and uses a softer synthetic partner.

Psycho vs Volkl V-Blast

Volkl V-Blast combines natural gut with V-Feel multifilament for maximum comfort and power. Psycho is more controlled and spin-oriented.

Final Verdict

Volkl Psycho Hybrid is a well-designed bridge between full polyester and multifilament. Cyclone supplies shaped control and spin, while Power Fiber II adds power, pocketing and touch.

The setup’s character depends on orientation, and its physical life is usually limited by the soft component. Those are normal hybrid tradeoffs rather than defects.

Cyclone mains are the logical starting point for established polyester users. Power Fiber II mains suit players who prioritize comfort and easy depth but still want a controlled cross.

Frequently Asked Questions
