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 balanced performance.

Vivo is built to be a balanced string from the start.

Zero and Sync sit at opposite ends of the spectrum, but when combined, they provide a complementary balance.

While both offer balance, how they get there creates big differences in power, spin, and connection.

This guide explains those differences so you can choose the right setup for your game.

Vivo Full Bed: Balanced Performer

Vivo is a shaped co-poly string built from recycled polyester that starts balanced and stays balanced.

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

Advanced players who can generate their own power and spin will find Vivo delivers exactly what they need.

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

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 forgiving.

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

Interestingly, 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 and can handle a firmer response.

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 balanced performance. Vivo starts balanced and stays balanced, while the hybrid blends two extremes to find balance.

Either way, you will be playing with a really high-level balanced string bed. But how you get there is where the difference lies.
