Butterfly
Rozena.
The missing step between control and high tension. Tenergy technology, but with enough tolerance to build the point instead of closing it.

Jumping straight to a high-end tensor rubber such as a Tenergy, however, is a risky bet, because those are merciless with technical error and require a player who has already reached a level that genuinely deserves to be called advanced. It was for that player that Butterfly created the Rozena.
Launched in 2017, the Rozena was not conceived as a little sister to the Tenergy range but as a rubber with a mission of its own: to bring part of the company's tensor technology to an audience still building an attacking game. The question this review sets out to answer is not whether the Rozena is as good as a Tenergy — it is not, and does not claim to be — but whether it plays well the role it was designed for, and who it really suits.
What the Rozena really is
It is worth starting by clearing up a common misunderstanding. The Rozena uses Spring Sponge, the tensor sponge Butterfly popularised with the Tenergy range, but it is neither a softer Tenergy nor a Tenergy with its performance trimmed back. Butterfly designed this rubber around a concept the brand itself calls "tolerance": the sponge is roughly one degree softer than the Tenergy 05's, the topsheet is somewhat less aggressive, and the pimple layout (with a 2.4 mm pitch) sits halfway between the Tenergy 05 and the Tenergy 64.
The result is a genuine tensor rubber — lively bounce, a high launch angle, a topsheet with plenty of grip though no tack — but with a markedly wider margin for error. Where a Tenergy punishes an imprecise stroke or a mistimed contact without mercy, the Rozena forgives. That is its real value proposition, and it explains why it is aimed at a particular player rather than at everyone.
On-table behaviour
Rallying and consistency
It is in the sustained mid-distance exchange that the Rozena is most convincing. A reasonably fast tensor sponge combined with a topsheet that grips the ball well produces safe topspins, with a high arc and a trajectory that lands on the table with room to spare. A player coming from a control rubber immediately notices the jump in speed and spin, but without that sense of riding a runaway horse that usually accompanies a first contact with a Tenergy.
That consistency is, technically, its greatest virtue: the Rozena allows fast play without giving up safety, a balance that is hard to find in this category.
Attack
Here it pays to be honest and temper the enthusiasm. The Rozena attacks well, but it is not a rubber for finishing points in a single stroke. It generates enough speed and spin to open the point and apply pressure, yet it lacks the devastating punch of a top-tier rubber when it comes to smashing or to hitting a genuinely powerful third ball. A player looking to close points with aggressive winners will find that the rubber goes along with them up to a point and then falls short.
Put another way: the Rozena is an excellent rubber for building the point and an adequate one for finishing it. Anyone whose game rests on raw power will feel limited; anyone who builds it on placement, active rallying and consistency will find a very effective ally.
Blocking and passive play
The block is solid and predictable, in keeping with the rubber's tolerant character. It absorbs the opponent's spin well and returns a stable ball without demanding fine adjustment of the bat angle. In the short game, being non-tacky, it is not the ideal tool for the player who lives on manipulating spin with very sensitive touches, but it copes comfortably with the receive and with backhand flicks, where the topsheet's good grip helps.
How it compares with the alternatives
The inevitable comparison is with the Tenergy 05, and the right framing here is not "which is better" but "which one fits". The Tenergy 05 offers more spin, more speed and a far higher offensive ceiling, but it demands settled technique and punishes error. The Rozena delivers a good part of that tensor sensation at roughly half the price and with far greater tolerance. For a player who has yet to master the topspin stroke reliably, fitting a Tenergy means paying over the odds for performance they cannot exploit and that will, on top of that, make consistency harder.
Against the classic control rubbers, the Rozena is a clear step forward in speed and liveliness. It is precisely the answer to that blandness described at the outset: it keeps much of the safety and adds the spark that was missing.
Within the intermediate-offensive segment itself it competes with options such as the mid-range tensor rubbers from other brands (for instance, the medium-hardness ESN sponges fitted to many rubbers from European manufacturers). The Rozena stands out in that group for the quality of its topsheet and the coherence of its behaviour, even if some rivals offer a touch more power in exchange for slightly less control.
Who it is for
The Rozena is clearly intended for the intermediate player in transition: someone who has already outgrown purely control-oriented rubbers and developed a functional topspin, but who does not yet play with the technical solidity that justifies a top-tier rubber. It is also a sensible choice for the consistent, placement-based player who, even at a decent level, puts safety and consistency ahead of maximum power.
It is not the rubber for the explosive attacker who lives on the smash, nor for the specialist in fine short-game manipulation. And it is certainly not an absolute beginner's rubber either: its lively bounce can be too much for anyone who has yet to control the basic stroke.
Pros
- A real balance between speed, spin and control
- Wide margin for error: it forgives imprecise strokes
- Accessible tensor technology at a contained price
- Light weight (~47 g), does not burden already fast blades
- Reasonable durability for a tensor rubber
Cons
- Limited offensive ceiling: not built for powerful smashing
- Less spin and speed than a Tenergy (~10–20%)
- Too little tack for short-game manipulation
- A player in progression can outgrow it quickly
Which blade to pair it with
The choice of blade is where a good rubber either shines or goes to waste. Being medium-soft, the Rozena asks for a blade with a degree of firmness and direction. The mistake to avoid is obvious: pairing it with a very soft, flexible blade — something along the lines of a Nittaku Acoustic — produces a set-up with an exaggeratedly high arc, a spongy feel and no pop, without that dry, direct response that inspires confidence. Soft rubber on a soft blade is softness piled on softness.
Beyond that, the range is wide. Butterfly officially recommends blades such as the Falcima and the Outerforce CAF. For the player fitting it on both sides and playing an offensive allround game, a classic five-ply all-wood blade like the P. Korbel, with the Rozena in 2.1 mm, makes a balanced set-up for topspin and point construction.
Another common misunderstanding is worth clearing up: that a tolerant rubber only works with slow blades. It does not. The Rozena gets on surprisingly well with carbon. An inner carbon blade such as the Innerforce Layer ALC, with Rozena on both sides, is a successful combination: the carbon supplies speed while the Spring Sponge still lets the ball sink into the sponge before it leaves, without the set-up losing its explosiveness. The firmness the Rozena needs can come just as well from a firm all-wood blade as from a carbon one.
On thickness: the 2.1 mm version offers the most speed and spin, and is the usual choice for the forehand; the 1.9 mm gains control for blocking, which makes it a sensible option for the backhand.

Rating by dimension
One of the most sensible recommendations in the Butterfly catalogue.
The Rozena does well what it promises to do, and in a market saturated with rubbers that promise more than they deliver, that alone counts for something. It is not a cheap Tenergy: it is a rubber with an identity of its own, designed for one specific stretch of a player's journey and honest about its limits. It offers the experience of a modern tensor rubber — lively bounce, good grip, high arc — with a margin for error that invites loose, fearless play, and all at a very reasonable price. Its only "flaw" is a consequence of its virtue: a player in full progression may end up asking more of it than it can give.
