Both are well-regarded Yasaka rubbers with great value, but they split on character. The Rakza 7 is a non-tacky tensor with huge grip, near-Tenergy spin, outstanding short-game control and no runaway catapult on touch, and it works on both wings with selectable thicknesses. The Rakza Z is a tacky hybrid with extreme, low-slip spin and long dwell that makes lifting backspin easy, but it is heavier and weak at less than full power.

Choose the Rakza 7 if you want a versatile, controllable rubber for either wing, especially as a backhand or a first step up from entry rubbers. Its speed is moderate, so you supply pace with stroke and placement.

Choose the Rakza Z if you are a forehand looper who swings fully and wants maximum spin and a strong linear kick. It needs a closed blade angle for its high throw and turns weak when you are out of position. The Rakza 7 is the all-rounder; the Rakza Z is the forehand spin weapon.

FAQ

Which has more spin?

The Rakza Z, rated extreme with its tacky topsheet and long dwell. The Rakza 7 is very spinny too, with reviewers putting its grip close to Tenergy 05, but it is non-tacky.

Which is better for the backhand?

The Rakza 7. It is one of the most recommended backhand rubbers at club level and works on both wings, while the Rakza Z is a forehand rubber that is weak at low power.

Which is heavier?

The Rakza Z at around 72g uncut, versus about 70g for the Rakza 7. The Z can also tire the arm on carbon blades, so weigh that against its extra spin.
