Opening against backspin
A clean forward-brushing stroke can lift effectively, but the hard sponge wants you to hit into it. Brush too softly and the ball may not carry enough quality; engage the sponge and the opening becomes fast and heavy.

Xiom Omega 4 Pro is an old-school attacking tensor with a distinctly lively click. Its Hyper Elasto topsheet and upgraded Carbo Sponge combine extra built-in tension with a firm 47.5° feel, producing high speed, strong spin, and a direct response when you hit into the sponge. It is a serious step up from Omega 4 Euro: more aggressive, more immediate, and much more rewarding when your stroke mechanics are ready.
Omega 4 Pro suits intermediate to advanced offensive players who want a firm European tensor for loops, drives, flicks, and counterattacks. It is especially effective for players who hit through the ball, appreciate an audible crisp contact, and want strong output without moving straight to the most expensive Japanese flagships. It can work on both wings, with many players finding its direct response useful on the backhand. Choose it when you generate your own acceleration and want the rubber to reward decisive technique.
Omega 4 Pro is not the easiest rubber for beginners, soft-touch specialists, or players who rely on slow brushing without much forward acceleration. The 47.5° sponge can feel hard and less forgiving on a flexible or very soft blade, and the immediate release gives you less time to correct a late racket angle. If you want a softer progression rubber, choose Omega 4 Euro or Rozena; if you want more modern dwell and grip for high-quality slow loops, look at Vega Pro or a newer premium tensor.

The Omega 4 Pro decision guide
Omega 4 Pro belongs to the generation of tensors that announce contact with a sharp click and a quick, energetic rebound. The Carbo Sponge gives it a speed-glue-inspired feel, while the firm topsheet keeps loops, drives, flicks, and smashes connected to a decisive stroke. It is not the softest or most forgiving modern rubber, but it remains compelling for players who enjoy direct feedback and want a hard-working offensive sheet at a more accessible price.
In play
The useful question is not whether Xiom Omega 4 Pro is simply fast or spinny. It is how the rubber behaves in the moments that decide a point.
A clean forward-brushing stroke can lift effectively, but the hard sponge wants you to hit into it. Brush too softly and the ball may not carry enough quality; engage the sponge and the opening becomes fast and heavy.
Omega 4 Pro has enough reserve for strong counterattacks, with a quick rebound that rewards a committed swing. It feels more direct than a soft, dwell-heavy rubber and asks you to keep your timing in front of the ball.
The crisp contact makes punch blocks and aggressive counters satisfying. Passive blocking is less forgiving on a fast blade, so close the racket and use a small active stroke against heavy topspin.
Flicks, drives, smashes, and quick topspin all benefit from the rubber's immediate release. It is a good fit for a player who wants to take time away, but less comfortable for delicate touch if the hand is loose.
The firm topsheet can produce useful spin and a clean short touch, but it is less naturally sensitive than newer grip-focused rubbers. You get the best receive when your racket angle and contact are deliberate.
Construction, translated
Creates a lively, tensioned response with enough grip for looping and flicking, plus the crisp contact Omega Pro is known for.
Adds the rubber's speed-glue-style click and releases energy sharply when the player accelerates into the ball.
Provides stability and power at impact, but requires more complete mechanics than a soft development tensor.
Makes fast attack and countering feel decisive, while reducing the time available to rescue a late or loose contact.
Sits between a pure control rubber and a modern pro-level flagship: aggressive enough for competition, but available at a more approachable price.
Build the racket around it
Omega 4 Pro is happiest on a blade that gives its hard sponge enough stability without making the short game too abrupt. A controlled five-ply, hinoki-topped, or balanced carbon blade can add dwell and feedback; a very stiff OFF+ blade will maximise power but narrow the margin for error.
Butterfly Petr Korbel; Stiga Offensive Classic
Adds dwell and touch to the immediate tensor response, helping loops feel less abrupt.
Butterfly Viscaria; Xiom Stradivarius
Gives Omega 4 Pro a stable platform for fast counters while preserving its click and directness.
Hinoki-topped or inner-carbon blades
Can balance the firm sponge and create more comfort for players who want offensive speed without an overly sharp first contact.
Buyer questions
Omega 4 Pro is the faster, firmer, and more direct version, with a 47.5° sponge and a stronger click when the ball engages the Carbo Sponge. Omega 4 Euro is softer and easier to control, making it better for developing technique and all-round play. Choose Pro when you already accelerate confidently and want more attack; choose Euro when you want the Omega family feel with a wider margin for error.
Both are firm offensive tensors, but Omega 4 Pro feels more immediate and clicky, with an older speed-glue-style rebound that rewards direct contact. Vega Pro generally gives a more supple, dwell-oriented response and can feel easier for controlled looping. Choose Omega 4 Pro if you like crisp impact, drives, flicks, and fast counters; choose Vega Pro if you want more time on the ball and a more modern all-round topspin feel.
Omega 4 Pro is a firm, direct European tensor with a strong click and fast rebound, while Tenergy 05 gives a more pronounced high-arc, spin-oriented response with a different kind of dwell. T05 is usually the safer choice for opening against heavy backspin and shaping high-quality loops; Omega 4 Pro is attractive for players who drive, counter, and hit through the ball. Choose based on stroke preference, not just speed ratings.
It can be excellent on the backhand for an intermediate or advanced player who uses active counters, flicks, drives, and compact topspin. The firm sponge makes the response stable and the quick release helps take time away, but passive blockers and players with late contact may find it demanding. Pairing it with a controlled or softer-feeling blade can make the backhand more manageable.
Usually not as a first rubber. The 47.5° sponge and immediate rebound reward correct acceleration but leave less room for loose racket angles, short strokes, and developing touch. A player stepping up from beginner equipment may enjoy Omega 4 Pro after regular coaching, especially with a controlled blade, but Omega 4 Euro, Rozena, or another softer tensor will generally make learning fundamentals easier.
