StarVie Eternal by Sanyo Gutiérrez

The StarVie Eternal by Sanyo Gutiérrez is tagged Professional and sold as adaptable. Yet its balance is only labelled Medium, and no review of it has turned up. So this page works from the specs alone. That is less than you would like. It is still enough to tell you what kind of racket this is.

Professional tag, Medium label: what a signature racket tells you on paper

StarVie names Sanyo Gutiérrez as the player behind it and lists the level as Professional. The brand also describes the player profile as "Versátil". Those two labels pull in different directions. Professional suggests a demanding racket. Versátil suggests something that suits many styles.

The specs help you choose between them. A stiff carbon face, a hybrid shape and a small sweet spot read as a racket for players who find the ball cleanly. Treat it as a demanding racket first.

Wide sweet spot and total adaptability, says StarVie: the meters read Low

The product page claims a wide sweet spot, a very adaptable response and a medium feel that combines power, control and comfort. Those are the brand's words, not measurements.

The meters on this page tell a different story. Sweet spot reads Low and comfort reads Low. Control, power and maneuverability sit at Medium. The sweet spot meter has no listed drivers, so treat that reading with some caution. Still, nothing in the published specs backs up a wide sweet spot. Until someone plays it and reports back, the brand claim and the spec reading stay in disagreement.

M-EVA-Balance under 18K Carbon Hybrid: why comfort reads Low and the rest Medium

The core is M-EVA-Balance. The product page calls it a medium-hard rubber. That raises control and comfort a little. The face is 18K Carbon Hybrid, which is carbon-stiff. It raises control and power, but it lowers comfort.

The result is a racket with no extreme. You get balanced control and power. You do not get a soft, forgiving touch. If your elbow or shoulder complains easily, take that Low comfort reading seriously. A stiff face passes more vibration to your arm. The product page mentions an anti-vibration handle rubber and an anti-shock grip. These are claims, and nothing here measures them.

350 to 370 g and a weight system: what you can adjust and what you cannot measure

The brand lists 350 g to 370 g and 38 mm thickness. The balance label is Medium, so do not expect a head-heavy swing.

The weight system is called Power Balance. According to the product page, it lets you shift the weight distribution with rubber pieces of different weights, which are included. That is the main adaptable part. The catch is that it is unclear how far the balance moves. The brand has not published the balance in mm, so the effect of each setting cannot be put in numbers. Expect to experiment. Change one thing at a time and give each setup a few sessions.

Eternal next to the Metheora+ and two Siux hybrids

The closest relative is the StarVie Metheora+. It shares the 38 mm thickness, the 350 to 370 g range, the hybrid shape and the M-EVA Balance core. Its face is 12K Carbon Hyper and its level is Intermediate. The meters differ in one place: comfort reads Medium there and Low here. If you like the build but want an easier arm, start with the Metheora+.

The Siux Electra St2 Stupa Pro is also tagged Professional, with a 15K carbon face and a medium HR rubber core. It weighs 355 to 375 g. Its maneuverability reads Low against Medium for the Eternal. The Siux Pegasus GV Edition is tagged Advanced, with a 24K Twill Silver Carbon face, 355 to 375 g and a 265 mm balance. It also reads Low on maneuverability. So the Eternal is the handier of the three on paper.

Balance in mm, head size, frame, handle: what StarVie does not publish

Four things are missing: balance in mm, head size, frame profile and handle dimensions. Each of them changes how a racket swings. Balance in mm would show how head-heavy the racket really is. Head size would say something about the sweet spot. The handle matters for grip comfort.

Without these, the label Medium is all you have. Ask a shop to measure the balance, or try a demo racket, before you decide. The brand lists the warranty as 3 years.
