The Head Coello Pro 2026 is aimed at intermediate attackers who want explosive overhead performance paired with a softer core touch. Both high-balance, 370-gram rackets favor aggressive players on the left side of the court looking to dominate at the net.

Which one has more power?
When comparing raw offensive capability, both models share our maximum power assessment rating of 5 out of 5. Each racket is engineered purely for power, combining a high balance with a total weight of 370 grams. This top-heavy weight distribution generates massive momentum on high-impact shots, making both rackets formidable tools for finishing points with smashes, deep aggressive bandejas, and sharp viboras.
The fundamental difference lies in how that power is delivered through their core structures. The Babolat Technical Viper uses a hard core (stated by the manufacturer and evaluated as hard in our assessment) along with a Carbon 16K/3K frame. This produces a stiff, dry impact where energy is directly transferred into the ball without dampening. On the other hand, the Head Coello Pro 2026 features a Power Foam core—which we rate as soft in our assessment—combined with a Carbon Hybrid face. While the head-heavy weight distribution and pure power score remain identical, the softer core in the Head racket offers a different feel on impact compared to Babolat's stiff construction.
Which is easier to play and control?
Neither of these rackets is built for easy handling or effortless touch. In our assessment, both the Babolat Technical Viper and the Head Coello Pro 2026 feature a small sweet spot. Off-center hits require precise technique, meaning players must contact the ball cleanly to maintain control and depth.
In defensive scenarios, such as retrieving low balls off the back glass, both frames demand solid physical effort. Their high balance and 370-gram weight shift the mass toward the head, which reduces swift maneuverability during quick wrist adjustments. When forced to defend deep in the court, players will find that neither racket is built to forgive late timing or poor footwork.
Regarding arm comfort, the core differences are key. The Babolat Technical Viper’s hard core and rigid frame offer minimal shock absorption, placing higher demands on the player's arm and joint stability. Conversely, because we rate the Head Coello Pro 2026 as having a soft core hardness, its Power Foam interior provides a more cushioned impact feel during fast exchanges.
How do they handle at the net and in overhead situations?
At the net, both frames perform at their best when accelerating through the ball. Aggressive volleys can be hit with tremendous pace thanks to the 370-gram weight and head-heavy balance. Left-side court players who constantly push forward to finish points will appreciate the mass behind drive volleys and overhead strikes.
In overhead situations like the smash or fast vibora, both rackets allow players to fully capitalize on their top-heavy balance. The Babolat Technical Viper rewards players who swing fast and hit clean, providing solid, stiff feedback off its carbon frame and hard core. The Head Coello Pro 2026 relies on its Carbon Hybrid face and soft Power Foam core to yield quick ball output, letting aggressive attackers crush overheads effectively.
