What Type of Rubber Is the JOOLA Rhyzer Pro 50?

The JOOLA Rhyzer Pro 50 uses a 50-degree 2.0mm sponge with built-in tension that catapults the ball at 9.5/10 speed and 10/13 spin on full strokes. At $35-50, the JOOLA Rhyzer Pro 50 sits in the competition tensor tier where rubber selection comes down to sponge hardness and trajectory shape rather than basic spin output.

The 75-degree throw angle keeps the ball on a flatter trajectory, ideal for counter-driving and over-the-table flicks where height costs the player time. The 50-degree hardness rewards full strokes: light brushing leaves energy in the sponge unused, while accelerated contact loads the rubber and snaps the ball forward. The trade is a steeper learning curve compared to softer tensor sheets.

How Does the JOOLA Rhyzer Pro 50 Compare to Butterfly Tenergy 05?

Spin output reaches 10/13 with the JOOLA Rhyzer Pro 50 versus 11.5/13 for the Butterfly Tenergy 05 at $35-50 versus $65-80. The JOOLA Rhyzer Pro 50 runs a 50-degree sponge against the Butterfly Tenergy 05’s 36-degree sponge, a difference that changes the rubber’s behavior on different stroke types.

Players who hit through the ball with full arm acceleration extract more from the JOOLA Rhyzer Pro 50 than the Butterfly Tenergy 05: the harder sponge stores energy that softer rubbers leak before contact ends. Players whose technique relies on a softer touch and longer dwell time get more spin from the Butterfly Tenergy 05’s lower hardness.

Which Blade Pairs Best with the JOOLA Rhyzer Pro 50?

The JOOLA Rhyzer Pro 50 pairs with stiff offensive blades that match its hardness. The Butterfly Viscaria at $150-190 with its 7-ply Arylate-Carbon construction handles the JOOLA Rhyzer Pro 50’s 9.5/10 speed without flexing under contact. All-wood blades soften the JOOLA Rhyzer Pro 50’s response, blunting the sponge’s energy transfer.

On the forehand specifically, the Butterfly Timo Boll ALC at $170-200 produces a slightly softer composite feel with similar speed. Players who use Chinese-style technique often pair the JOOLA Rhyzer Pro 50 with the Butterfly Viscaria for a setup that matches the National Team’s hardware profile.
