The Dignics 80 is the faster, more versatile sheet, balanced on both wings with very high speed and spin and a lively catapult that suits two-winged loopers. Control is only medium and the price is premium.

The Rakza Z is a tacky hybrid built for spin. Its grippy topsheet and extreme spin make it easy to lift heavy backspin, with surprisingly high control and long dwell for a hard rubber and a strong, linear kick when you commit to a full stroke. The catch is that it is heavy and can cause arm fatigue, has a high throw that needs a closed blade angle, and goes weak and slow at less than full power or when out of position.

Choose the Dignics 80 for all-round speed and balance on either wing with fast arm speed. Choose the Rakza Z if you are a proactive forehand looper who swings fully and wants heavy tacky spin, or a budget-minded player who likes the feel of Dignics 09C or boosted Hurricane 3.

FAQ

Which rubber spins more?

The Rakza Z is rated extreme spin thanks to its tacky hybrid topsheet, making it easier to lift heavy backspin. The Dignics 80 is very high spin but relies more on a tensor catapult than tackiness.

Is the Rakza Z good on the backhand?

It is best as a forehand rubber for proactive loopers who swing fully. The Dignics 80 is the more natural two-winged choice since it is strong on both forehand and backhand.

Which is more demanding to use?

Both reward good technique. The Rakza Z is heavy, has a high throw needing a closed angle, and goes weak and slow at less than full power. The Dignics 80 demands clean technique and fast arm speed but is faster across the board.
