Our Signum Pro Tornado string test

Power and control

This string is perfect for all-rounders looking for an excellent compromise between control and power.

Spin

It is a twisted monofilament with 7 faces for optimal spin. Players with a penchant for cambered trajectories will be delighted.

Comfort and forgiveness

At impact, Signum Pro Tornado strings show their flexibility. In fact, forearm trauma is limited by its comfort. The smaller the gauge, the more comfortable you'll feel. You'll also benefit from excellent forgiveness on off-center balls. The ball will bounce back thanks to the trampoline effect offered by the softness of the string, and comfort will always be there.

Durability and tension hold

With this structured monofilament string, tension hold is excellent. Life expectancy is standard for this type of set. Opt for a thicker gauge for greater strength and durability.

Sensation / feel / stiffness

We'd describe the feel of the string as fine. The feel is also very good. Finally, stiffness is on the low side, with softness and comfort predominating for an incredible feel when striking.

Tip Extreme Tennis:

This string should not be over-stretched. Keep standard tension at around 23k, even on fine gauges, to preserve the string's intrinsic properties.

WHAT TYPE OF PLAYER IS SIGNUM PRO TORNADO DESIGNED FOR?

We recommend this string for players looking for comfort in their game. However, it is also perfectly suited to players who like to give a maximum of spin on each of their shots.

End-of-court lifters who like to direct exchanges by making their opponents back off thanks to long, curved trajectories will be able to choose this string without hesitation.

However, players of all levels looking for comfort and excellent value for money will be equally satisfied with the Tornado.

Where does the TORNADO string stand in the Signum Pro range?

This string offers the best balance between playing comfort, ball rotation and excellent tension hold. All at a very attractive price.

Highlights :

  • Spin
  • Comfort
  • Control/power balance

    Nice spin control that adds weight to the ball. I would like a thinner gauge but maybe durability would suffer. (Translated review)

    Belle prise d'effets qui donne de la lourdeur à la balle. J'aimerais une jauge plus fine mais peut-être que la durabilité s'en ressentirait.
