Vivo Full Bed vs Zero and Sync Hybrid

August 6, 2025 Juan

We recently got a customer email asking about the difference between a full bed of Vivo and a hybrid of Zero and Sync.

This question comes up often because both setups deliver control and spin in different ways.

Vivo is built as a control and spin string from the start.

While, Zero and Sync sit at opposite ends of the spectrum.

Zero offers fantastic power and spin, and Sync prioritizes control and feel. When combined, they give a great blend of control and spin.

This guide explains the nuanced differences so you can choose the right setup for you.

Vivo Full Bed: Control and Spin

Vivo is a shaped co-poly string built from recycled polyester that delivers exceptional control and spin with a crisp, firm response.

This string offers a more direct feel that gives you clean, immediate feedback and tour-level responsiveness on every shot.

The string focuses on bite rather than pure snapback for spin generation, providing that hexagonal grip on the ball without excessive string movement.

Because it lacks the slick snapback of Zero and Sync, think of Vivo as a string that amplifies your existing skills rather than compensating for areas where you need help.

Zero x Sync Hybrid: Dynamic Duo

This hybrid setup combines Zero in the mains with Sync in the crosses. Zero brings hexagonal power and spin while Sync adds round control and feel.

The setup works by balancing two extremes.

Zero on its own can be too powerful for some players, while Sync alone might not provide enough pop.

Together, they create a middle ground that's more controllable and forgiving.

The good thing about this setup is you get lots of snapback from both strings. The slippery nature of Zero and Sync creates more string movement and spin potential.

Note that this setup is used by WTA pro Cristina Bucsa.

Performance Comparison

Factor	Vivo Full Bed	Zero x Sync Hybrid
Power	You generate it	Power generation from Zero
Spin	Bite from Vivo	Snapback from both, Bite from Zero
Connection	Direct feedback	More string movement
Sustainability	Recycled polyester	Virgin polyester

Power

With Vivo, you create the power through your swing technique and timing. The Zero x Sync hybrid actively helps generate power through Zero in the mains.

Spin

Vivo provides bite through its hexagonal shape, giving you grip when you create the spin yourself. The hybrid setup delivers snapback from both strings, and bite from Zero.

Connection

Vivo gives you direct, immediate feedback that suits more advanced players. The hybrid allows more string movement, creating more assisted spin but less direct connection.

Sustainability

Vivo is made from recycled polyester, giving it an advantage in sustainability. Zero and Sync are both virgin polyester. However, both play better for longer than traditional polys, meaning less restringing.

What Setup Should You Choose?

Choose Vivo Full Bed

Choose Vivo if you're an advanced player who can generate your own pace and spin. This string rewards players who want direct feedback, precise control and gripping spin.

Choose Zero x Sync Hybrid

Choose the Zero x Sync hybrid if you want more assistance with power and spin generation. This setup is more user-friendly while still delivering high-level performance.

Conclusion

Both setups end up in a similar place in terms of delivering control and spin.

Vivo starts there, while the Zero x Sync hybrid blends two extremes to find balance.
