Donic Waldner Off World Champion 89 - Another great blade within this series
Twenty-five years after their spectacular success at the table tennis world championship in 1989, Donic honors the players from back then with creating three new World Champion 89 blades. The
Donic Waldner Off World Champion 89 was dedicated to Jan-Ove Waldner, the "Mozart" among table tennis players.
Within the blades of this series, the veneers are dried via a recently developed
cold-pressing process. This allows to reduce the amount of moisture within the material up to 4%. Due to this, the material is dimensionally very stable during and after the manufacturing process.
The
materials used for the Waldner Off are the same as in the faster Persson Off+: 1.0 mm Italian spruce, 0.8 mm spruce, 3.0 mm kiri, carbon-fleece zylon (cfz), 0.8 mm spruce, and 1.0 mm Italian spruce (more details on these materials further below). However, there is a
difference with respect to the veneer arrangement in order to obtain more control and a better feedback/feeling compared to the Off+ version. The cfz layers of the Waldner Off are not located between the outer and inner veneers, but between the inner and the core veneer. This results in a
harmonic feeling for the game with a
balanced mix based on speed and control. Consequently, returns and blocks during passive situations go off the hand in a controllable manner with much precision even for sensitive strokes.
Of course, the Donic Waldner Off World Champion 89 also has
enough power for offensive strokes. This allows you to easily perform topspins and shots, for example. All in all, this Donic blade is recommended for variational attackers who are still preferring a good feeling for game when doing passive strokes. The corresponding gaming style is the
controlled offensive (Off-) and the offensive (Off), also depending on the rubbers you select.
Donic Waldner Off World Champion 89 - A closer look at the materials
As already mentioned, we now would like to have a closer look at the materials used in the Waldner Off World Champion 89.
Let us first get started with the heart of this blade, the core veneer. This veneer is made of
Kiri wood. Kiri is a tree native to Central and West China. However, cultivations of this tree can also be found in Japan, Korea or North America. The tree may reach a height of approx. 15 m. Kiri is quite light (density: 300 kg/m
3), not very strong (Young´s modulus: 4,380 N/mm
2), and not very hard (Janka hardness: 250). Kiri veneers are
denser, more durable, and harder than e.g. Balsa layers. Hence, Kiri plies are heavier and faster than Balsa plies. This underlines the suitability of Kiri to support more offensive strokes. Still, Kiri always exhibits
good control and feedback!
Next to the core veneer, we can find layers of
Carbon-Fleece-Zylon fabric (layers 2+4). This material is quite new, innovative, and is exclusively produced for Donic. As you might already know,
Carbon fibers (made of the element C) are
very light, but at the same time
extremely strong and stable. Hence, the whole blade becomes stiffer, more direct, and more dynamical.
Finally, (Italian)
Spruce is the third type of material used in the Donic Waldner Off World Champion 89 (layers 3+5+outer plies). Spruce (Picea abies) is native to Europe (except the British Isles and the Iberian Peninsula), but also to large parts of Asia. Spruce trees can reach an age of 600 years, a height of approx. 60 m, and a trunk diameter of approx. 2 m. The trees grow very quickly, and they are very frost-resistant during the cold months. Spruce is
heavier (density: 420 kg/m
3),
clearly stronger (Young´s modulus: 11,000 N/mm
2), and
slightly harder (Janka hardness: 300) than Kiri. In general, Spruce veneers offer much feedback and control. However, as is evident by the above-mentioned properties, spruce also supports offensive strokes! According to the manufacturer specifications, Donic uses trees with an age of more than 200 years for this blade (Italian Spruces). Also, the so called
SPT technology (Spruce Pressing Technology, made in Germany) is applied. Please also note that when combining Spruce with more offensive materials, like Carbon, the properties are clearly directed toward more offensive features.
