Adidas Metalbone HRD+ 3.4 vs Babolat Viper Soft Juan Lebrón 3.0

“The Adidas Metalbone HRD+ 3.4 2025 carries the Metalbone name into round-head territory, pairing an EVA foam core with a carbon face to produce a surprisingly explosive option for intermediate players. Power at 92 is exceptional for this level, and smashes off the back glass come out fast and heavy. Control at 72 and comfort at 64 are the compromises: expect some arm feedback and be ready to work for placement. PRR score: 89/100.”

“The Viper Soft Juan Lebrón 3.0 takes the same 365g Black EVA formula that already works on the Technical Viper Soft and wraps it in Juan Lebrón's signature diamond shell. Power eases back from the standard Viper JL's tour-level peak to a still-strong 82, and in exchange control and comfort both climb into the high 70s/80s — a genuinely balanced racket rather than a compromise. Maneuverability improves too, so the head-heavy diamond feels less punishing to hustle at net. The catch is coverage: it is stocked at a single retailer so far, and priced at parity with the far more aggressive standard Viper JL, so this is not the discount play the Technical Soft is.”
