Balsa 3.5 DEF+
TSP Balsa 3.5 DEF+ is engineered for the modern defensive player who values control and feel but wants the option to attack. Its lightweight build centers on a 3.5mm balsa core, reinforced with fiberglass veneers to expand the sweet spot, increase dwell time, and dampen vibration. This design delivers precise chops and blocks while retaining enough responsiveness for confident counter-attacks. It's a consistent, comfortable blade that excels in spin variation and placement, making it a favorite for players who blend defense with opportunistic offense.
The blade features a 5-ply construction with a central 3.5mm balsa core. This core is sandwiched between two layers of fiberglass, with outer wood plies. This 'Balsa-Glassfiber System' aims to create a spring-like effect for precision and control while minimizing vibration and maximizing the sweet spot.

✦Our expert analysis of this blade's performance characteristics
Designed for defensive play, the Balsa 3.5 DEF+ offers enough speed for controlled attacks and counter-hits. The balsa core and fiberglass layers create a responsive feel that lets players generate pace when needed without sacrificing the control essential for defense. It operates comfortably in the ALL- to OFF- range, perfectly suited for modern defensive styles that include attacking.
Control is the hallmark of this blade. The soft balsa core, fiberglass layers, and enlarged sweet spot deliver exceptional ball feedback and stability. This allows for precise placement of defensive shots like chops and pushes, as well as controlled blocking and well-timed counter-attacks. Players report great control without losing the ability to speed up when attacking.
The balsa wood core provides a soft, responsive foundation, enhanced by the fiberglass layers. This creates a comfortable touch on the ball, allowing players to clearly feel spin and trajectory—a crucial asset for developing a sensitive, controlled game.
When paired with certain rubber combinations, especially softer inverted rubbers, the blade can produce a medium-high throw angle. This is beneficial for generating heavy spin on powerful loops and defensive chops.
The extended contact time between ball and blade, a characteristic of balsa constructions with added fiber, allows for significant spin generation and enhanced control. This longer dwell time benefits looping, chopping, and delicate touch shots.
This blade offers a moderate level of flexibility. The balsa core provides springiness, while the fiberglass layers add stabilizing stiffness. This balance supports both controlled defensive strokes and more powerful offensive shots.
The balsa core combined with fiberglass is designed to minimize vibration, leading to a more comfortable and precise playing experience. While some feedback vibration remains, it is generally well-dampened compared to stiffer, non-balsa blades.
TSP is known for quality manufacturing, and the Balsa 3.5 DEF+ upholds that reputation. The materials, particularly the balsa core and fiberglass integration, are noted for their durability and consistent performance. Many users find these blades last for years, offering reliable play session after session.
Technology
TSP Balsa 3.5 DEF+ incorporates the proprietary 'Balsa-Glassfiber System.' This technology centers on a vertically aligned 3.5mm balsa wood core, known for its exceptional lightness and soft feel. The core is reinforced on either side with fiberglass layers. The fiberglass provides increased stability, a larger sweet spot, and a more consistent bounce, while the balsa core contributes to extended ball dwell time and reduced vibration. Together, they create a unique blend of control, feel, and transitional capability between defense and offense.
