What Type of Rubber Is the Yasaka Rakza 7 Soft?
The Yasaka Rakza 7 Soft uses a 40-degree 2.0mm sponge with built-in tension that catapults the ball at 8/10 speed and 9/13 spin on full strokes. At $25-35, the Yasaka Rakza 7 Soft 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 40-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 Yasaka Rakza 7 Soft Compare to Butterfly Tenergy 05?
Spin output reaches 9/13 with the Yasaka Rakza 7 Soft versus 11.5/13 for the Butterfly Tenergy 05 at $25-35 versus $65-80. The Yasaka Rakza 7 Soft runs a 40-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 Yasaka Rakza 7 Soft 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 Yasaka Rakza 7 Soft?
Mid-stiffness blades match the Yasaka Rakza 7 Soft most cleanly. The Butterfly Timo Boll ALC at $170-200 offers an Arylate-Carbon layup that supports the Yasaka Rakza 7 Soft’s 8/10 speed without overpowering it on touch shots. All-wood blades like the Yasaka Sweden Extra keep the setup more controlled for developing players.
On the backhand, players often pair a softer rubber with the Yasaka Rakza 7 Soft on the forehand, balancing offensive capability with backhand stability. The Butterfly Korbel at $69 offers a control-leaning all-wood option that pairs well with the Yasaka Rakza 7 Soft for intermediate players.

The Yasaka Rakza 7 Soft matches players rated 1400-2000 USATT who train regularly and have stable looping mechanics. At $25-35, the rubber sits in the competition tier where rubber selection follows playing style rather than budget.
How does the Yasaka Rakza 7 Soft compare to Butterfly Tenergy 05?
The Yasaka Rakza 7 Soft reads 9/13 spin against 11.5/13 for the Butterfly Tenergy 05 at $25-35 versus $65-80. The Yasaka Rakza 7 Soft fits players who want a harder, more direct sponge response without paying tournament-level prices.
How long does the Yasaka Rakza 7 Soft last?
The Yasaka Rakza 7 Soft maintains peak performance for 50-80 hours of competitive play, which translates to 2-4 months for players who train 3-5 sessions per week. Recreational players who play once weekly can expect 6-12 months before noticing reduced grip on the topsheet.
