Comparing the Babolat Viper Lebron 2.5 and Adidas Metalbone 3.4 HRD+ in detail
The channel dives into a highly anticipated comparison between two of the most sought-after padel rackets for advanced players: the Babolat Viper Lebron 2.5 and the Adidas Metalbone 3.4 HRD+. Both models have been recently updated and are positioned at the top of their respective brands’ lineups, drawing attention from players looking for maximum performance and the latest technology on court.
Key specifications and technical differences
- Babolat Viper Lebron 2.5 weight: 372g
- Adidas Metalbone 3.4 HRD+ weight: 365g
- Babolat Viper Lebron 2.5 balance: 27.1 cm
- Adidas Metalbone 3.4 HRD+ balance: 27.3 cm
- Core: Lebron features a harder core; Metalbone HRD+ uses a medium core
- Shape: Both rackets have aggressive, attack-oriented shapes, but the Lebron 2.5 is no longer labeled “Technical” and now resembles the classic Viper Carbon profile
Both rackets are considered premium, with high street prices and advanced materials. The Metalbone’s head-heavy balance and slightly lower weight contrast with the Lebron’s higher mass and more centralized feel. These differences influence playability and suit different player preferences.
Ball output and sweet spot comparison
When it comes to ball output, the reviewer finds the Adidas Metalbone 3.4 HRD+ to be superior, especially for players seeking easy power. The Metalbone’s head-heavy design and medium core provide more assistance in generating pace, making it more forgiving and “generous” in this aspect. The Lebron 2.5, with its harder core, can match the Metalbone in full-power shots but generally requires more from the player to extract the same level of ball speed.
In terms of the sweet spot, both rackets are close, but the Metalbone edges ahead with a slightly larger and more accessible hitting area. The Lebron 2.5 is described as a bit less forgiving at times, demanding more precision from the player.
Control, maneuverability, and comfort on court
For control, the reviewer gives the advantage to the Viper Lebron 2.5. Its response is more immediate and predictable, allowing advanced players to direct the ball with greater confidence. The Metalbone, while powerful, can be more reactive and requires careful handling to maintain accuracy.
On the topic of maneuverability, the Lebron 2.5 is favored, particularly in its standard configuration. The Metalbone’s head-heavy setup can feel cumbersome over long sessions, especially if the player is sensitive to weight distribution. However, removing some of the adjustable weights from the Metalbone can improve its handling, though this comes at the cost of some power and stability.
Regarding comfort, the Metalbone 3.4 HRD+ is described as slightly more comfortable, offering a softer impact and less harshness on contact. The Lebron 2.5, while improved over previous years, still has a firmer, drier feel that may not suit everyone, especially those prone to arm discomfort.
Power, spin, and performance in attacking shots
Power is a nuanced category in this comparison. The Metalbone 3.4 HRD+ provides more accessible, “automatic” power for the average player, thanks to its mass and core. However, the Lebron 2.5 shines when the player can accelerate the racket head and generate their own force—its harder core responds with explosive results for those with a fast arm.
For spin, both rackets are on par, with the Metalbone being marginally easier to use for generating spin, but neither stands out dramatically over the other in this respect.
When it comes to volleys and smashes, the Lebron 2.5 is highlighted for its solid, energetic response—especially in flat smashes and powerful overheads. The Metalbone, with its medium core, is more forgiving and easier to use for players who rely on the racket’s help rather than pure arm speed. The reviewer notes that the choice here depends heavily on playing style: those who “hit through” the ball with force may prefer the Lebron, while those who guide or brush the ball might favor the Metalbone.
Stability and baseline play for advanced users
Both rackets offer excellent stability, but the Metalbone’s extra mass in the head gives it a slight edge in this area. From the baseline, the Metalbone is described as more generous and easier to use, especially for players who want a bit more help in defensive situations. The Lebron 2.5, while less forgiving, rewards advanced technique and offers a more direct, precise response for those who can handle its demands.
Summary of key qualitative evaluations

Which racket suits which player profile?
The reviewer emphasizes that both rackets are best suited for intermediate to advanced players who can handle their weight and performance characteristics. The Metalbone 3.4 HRD+ is recommended for those seeking more help from the racket, especially in terms of power and forgiveness. The Viper Lebron 2.5 is ideal for players who generate their own force and value maneuverability and control, particularly in fast exchanges and attacking volleys.
Ultimately, the choice comes down to personal style and physical preference. The reviewer personally prefers the handling and movement of the Lebron 2.5, despite appreciating the Metalbone’s aesthetics and ball output.
