Wieder ein paar für die Liste:
Yasaka Extra 3D 1303 Hz, 87 g (etwas fraglich, da das Holz nach weniger als 3 Stunden Einsatz an den Einschnitten im Holz angebrochen war)
Yasaka Sweden Extra 1324 Hz, 84 g mit "Griffband", ohne 82 g
729 F-1, 1383 Hz, 81 g mit "Griffband", ohne 78 g

Hölzer mit "Griffband" gemessen, das Extra 3D und die alten Powerplays früher im Thread ohne. Griffband: Kinesiotape.

Vibrations of table tennis racket composite wood blades: modeling and experiments,
Lionel Manin, Marc Poggi, Nicolas Havard (letzter Cornilleau), 2012
"The detailed composition of the plywood can be taken into account in the modeling but it does not lead to better results than the modeling of one equivalent homogenized orthotropic wood layer. The plywood elasticity properties have been determined by experiments and implemented in the FE modeling. The results obtained by experiments
have shown a good agreement with the simulation for the resonance frequencies and there associated vibration modes."

Vibro-acoustic of table tennis rackets at ball impact: influence of the blade plywood composition, Lionel Manin, Florian Gabert, Marc Poggi, Nicolas Havard, 2012
"There is a clear decrease (~30%) of the vibration frequencies when the rubbers are glued on the racket blade (Fig. 4). An analysis done with the laser vibrometer has confirmed that the modes were remaining the same for the racket blades with of without the rubbers glued on. It appears that the rubbers damp more the membrane mode than the chips mode."

Vibro-acoustic of table tennis rackets. Influence of the plywood design parameters. Experimental and sensory analyses, Lionel. Manin, Marc Poggi, Cyril Bertrand, Nicolas Havard, 2014
"It was shown that it is more the thickness of each wood ply that influences the vibro-acoustic than the wood essence used. The vibro-acoustic frequencies of the racket blades vary linearly with the ply thickness. A sensory analysis, implying high level players, was conducted. The players were asked to classify the rackets by sound similarities for two criteria: plain/hollow and low sharp sound. The comparisons between the sensory analysis and the vibro-acoustic laboratory experimental results have shown a good consistency. Moreover it appears that the ball impact sharpness can be related to the membrane mode vibration frequency of the racket blade."
