Design, construction, and technical specifications of the Siux Trilogy Pro 4
The reviewer begins by highlighting the Siux Trilogy Pro 4’s notable design updates and technical features. The racket features a green 24K carbon fiber face, which not only enhances its visual appeal but also contributes to a firmer, more responsive feel. The core is made from medium EVA rubber, providing a balance between control and power. A significant addition this year is the pronounced 3D roughness on the racket’s surface, intended to improve spin and ball grip.
- Weight range: 360–375g (tested model: 363g)
- Balance: 26.5 cm (medium-high)
- Face material: 24K carbon fiber
- Core: Medium EVA
- Grip: Standard size with Dual Pro Grip sock-out for vibration reduction
- Wrist strap: Rope type, less padded than usual
The heart of the racket features a robust central reinforcement, which adds rigidity without making the racket uncomfortable for the non-dominant hand. The reviewer notes that the handle narrows in the lateral area, making the racket feel thinner and easy to grip. The overall construction aims to balance comfort, control, and a slightly stiffer response compared to previous Trilogy models.
Handling and sweet spot: expectations versus reality
When discussing handling, the channel notes that the Siux Trilogy Pro 4 offers a standard level of maneuverability. The medium-high balance (26.5 cm) and the tested weight of 363g result in decent handling, but the reviewer expected a bit more agility, especially at higher weights. Players seeking exceptional maneuverability might find the racket somewhat average in this regard, particularly if they opt for models closer to the upper end of the weight range.
The sweet spot is described as standard in size and well-centered. The difference in response between hitting the center and striking outside the sweet spot is noticeable. Centered hits deliver good energy return and ball speed, while off-center shots feel drier and less powerful. This characteristic rewards precise technique but may challenge players who rely on a larger, more forgiving sweet spot.
Performance in defense: comfort at medium and low pace
In defensive play from the back of the court, the reviewer finds the Siux Trilogy Pro 4 to be comfortable and easy to use, especially at medium and low speeds. The medium EVA core helps generate ball speed without requiring excessive effort, making the racket suitable for players who prefer a controlled, steady pace. The reviewer appreciates how the racket directs the ball accurately and provides a pleasant feel when not hitting too aggressively.
However, when the intensity increases and the player hits flatter and harder, the racket’s response becomes noticeably drier. The reviewer mentions that in these situations, the racket absorbs more of the impact, requiring extra force to achieve the desired ball speed. This trait enhances control but may frustrate players seeking effortless power from the baseline.
Mid-court and spin: strengths and inconsistencies
In the mid-court, particularly during víbora and tray shots, the racket performs well at moderate effort levels. The reviewer notes that players don’t need to exaggerate their swing to achieve depth, as the racket’s rubber assists in generating sufficient ball output. Handling remains comfortable, and the racket does not tire the arm.
One standout feature is the pronounced 3D roughness on the face, which significantly enhances spin. The reviewer highlights how this roughness helps the ball drop earlier and adds weight to sliced shots. However, the sweet spot’s central placement means that shots struck higher on the face feel much drier and lack depth, resulting in inconsistent sensations. The reviewer experienced moments where a series of well-controlled, dry-feeling shots were followed by a sudden, overly bouncy ball when contact shifted lower on the face. This variability requires players to be mindful of their contact point to maintain consistency.
Volleying: best sensations and control at medium pace
According to the reviewer, the volley area is where the Siux Trilogy Pro 4 delivers its best sensations. The racket’s handling is described as standard, allowing for quick reactions and directional changes without lag. The sweet spot is less problematic here, but the reviewer still notes a tendency to hit outside it more often than with other rackets, which can reduce consistency.
At medium and low speeds, the racket offers excellent control and comfort, making it easy to place volleys with precision. When increasing intensity and playing with more slice, the racket’s roughness allows for heavy, controlled shots. However, when hitting flatter and harder, the face absorbs more of the impact, slightly reducing ball speed compared to other options. The reviewer concludes that the racket is best suited for players who favor controlled, sliced volleys over flat, aggressive ones.
Smash and finishing: power depends on precision
In the finishing area, the Siux Trilogy Pro 4 reveals its control-oriented nature. The reviewer found it challenging to adapt to the racket’s sweet spot, especially when attempting to generate maximum power. Shots struck in the central area benefit from the EVA core’s rebound, delivering standard power for a medium-hardness control racket. However, when contact is made higher on the face, the response becomes much drier and less explosive, making it difficult to achieve the desired power even with extra effort.
The reviewer suggests that players accustomed to control-format rackets and who consistently strike the central sweet spot will have a better experience. Those coming from more attack-oriented models may struggle to extract maximum power, particularly if their technique favors higher contact points.
Ideal player profile and comparative insights
The channel positions the Siux Trilogy Pro 4 as a strong option for intermediate players seeking a comfortable, control-oriented racket that assists in defensive play and offers reliable ball output at moderate speeds. The reviewer recommends it for players who value spin and control over raw power, particularly those who play at a medium pace and benefit from the racket’s pronounced roughness.
For more offensive or aggressive players who prioritize finishing and rapid attacking play, the reviewer suggests alternatives such as the Babolat Vertex 4, AT Attack, or Veron Technical, which provide a livelier response and greater power at high speeds.
Summary of key qualitative evaluations by court area
- Volley area: Best sensations, excellent control, and comfort at medium pace, especially with sliced shots.
- Defense (back of the court): Comfortable and easy to use at medium and low speeds; requires more effort for power at higher pace.
- Finishing (smash): Standard power for a control racket when hitting the sweet spot; drier and less responsive when contact is higher on the face.
- Mid-court (víbora/tray): Good spin and control, but inconsistent response depending on contact point; pronounced roughness enhances slice.
Overall, the Siux Trilogy Pro 4 stands out for its comfort, control, and spin potential, making it a compelling choice for players who prioritize precision and consistency over sheer power.
