The flex rating of a racket influences how power is generated and how the shuttle responds at contact. It plays a major role in playability, especially during smashes, drives, and defensive lifts.
Both rackets share a flexible profile. This means that neither one has a built-in advantage regarding shaft bend behavior. Flexible shafts bend more easily during a swing, returning stored energy into the shuttle. This helps players generate effortless clears and lifts even without high swing speed. They reduce fatigue over long sessions and support defensive recovery, though they sacrifice some precision during hard hits. Users comparing these two rackets may instead feel differences more from balance, weight distribution, and string setup rather than flex alone.

Balance affects swing sensation, shot recovery, and how easily power transfers into the shuttle. Even a similar weight racket can feel completely different depending on where the mass is distributed.
Both rackets share a head heavy balance profile, meaning their weight distribution philosophy is similar. Head-heavy rackets shift more mass toward the frame, increasing momentum behind smashes and clears. Players who dominate from the rear court or rely on offensive pressure benefit most. However, head-heavy setups may feel slower when switching quickly between forehand and backhand defense.. In this case, differences in performance will rely more on flex, weight class, and tension settings rather than balance alone.

The weight class determines how quickly a racket moves during defense and how much stability it has during smashes. Lighter frames accelerate faster, while heavier ones provide more impact stability.
Astrox 77 Play is available in 4U while Axforce 70 comes in 4U, 5U. A player choosing between them may decide based on whether they prioritize fast exchanges and net interceptions or power-focused shooting from the backcourt.
Lighter variants like 5U/6U emphasize maneuverability, especially valuable in doubles, defence and drive rallies. Meanwhile, 3U/4U variants carry more swing momentum, benefiting aggressive singles players who rely on steep smashes.

String tension capacity affects how the shuttle feels on contact. Higher tension enhances precision but requires strength, while lower tension increases repulsion and shuttle height support.
Astrox 77 Play is rated up to 28 lbs, while Axforce 70 supports 30 lbs. A higher tension range suggests better control headroom for advanced setups, whereas lower tension limits may feel more user-friendly for newer players.
Choose the lighter model for fast defense and doubles pace. Choose the heavier model for stronger smash stability and backcourt dominance.
