What Type of Rubber Is the Butterfly Rozena?

The Butterfly Rozena uses a 35-degree 2.1mm sponge with built-in tension that catapults the ball at 8/10 speed and 9/13 spin on full strokes. At $35-45, the Butterfly Rozena 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 35-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 Butterfly Rozena Compare to Yasaka Mark V?

Spin output reaches 9/13 with the Butterfly Rozena versus 8/13 for the Yasaka Mark V at $35-45 versus $20-28. The Butterfly Rozena runs a 35-degree sponge against the Yasaka Mark V’s 40-degree sponge, a difference that changes the rubber’s behavior on different stroke types.

Players developing competitive technique find the Butterfly Rozena’s softer sponge more forgiving than the harder Yasaka Mark V: contact angle errors of 5-10 degrees still produce playable returns. Players with stable mechanics gain peak performance from the Yasaka Mark V’s harder construction at the cost of reduced consistency on imperfect strokes.

Which Blade Pairs Best with the Butterfly Rozena?

Flexible all-wood blades complement the Butterfly Rozena’s softer sponge. The Butterfly Korbel at $69 with its 5-ply construction and 8.5/10 control rating pairs cleanly for developing players. Stiff carbon blades amplify the rubber’s softness into uncontrolled rebound.

For full beginner setups, the Yasaka Mark V on a Yasaka Sweden Extra blade remains the recommended starter combination at $60-80 total. The Butterfly Rozena fits between basic Mark V setups and harder competition rubbers in the upgrade path.
