Badminton racket strings are an essential part of your equipment that can significantly impact your gameplay. They are the only point of contact between the shuttlecock and your racket and are vital to a player’s ability to strike the shuttle effectively. Strings are usually made up of nylon, a durable synthetic material that is easily available and budget-friendly.

Types of Strings:

Power Strings are great for players who want maximum repulsion while hitting the shuttlecock. They have a thinner string diameter gauge of 0.68 or below.
Control Strings, on the other hand, have a textured finish that helps you get more feel while hitting the shuttle and allows for more controlled, spin and sliced shots.
Durability Strings, as the name suggests, are suitable for players who want their strings to last longer and have a diameter of around 0.7 gauge or more.
Factors to Consider When Choosing a String:

String gauge refers to the thickness of the strings and impacts the feel and texture of the strings.
The feel of the string is determined by the core and coating of the string and can be soft, medium, or rigid.
Resilience/Durability is particularly important for players who often break down their strings, and they should opt for thicker strings.
Repulsion is crucial for players looking for durable and repulsive strings.
Control and Power is important for players looking for a combination of both in their strings.

Yonex Exbolt 63 and Yonex 65 Exbolt 
Yonex is releasing a new badminton string called the Exbolt 65 in August 2022. The reviewer has tested the Exbolt 65 and found that it is smooth and easy to string, but it’s not as forgiving as other strings if you hit the ball incorrectly. The Exbolt 65 is also slightly thicker than its predecessor, the Exbolt 63. Additionally, the Exbolt 65 has better power and durability compared to the Exbolt 63, but it can vibrate the racket if the ball is not hit in the sweet spot. Overall, the Exbolt 65 is a good option for players who prefer smooth strings.

Yonex Exbolt 63
The Yonex Exbolt 63 is a new badminton string product for 2021. It has an outer casing made of Forged Fiber material that promises amazing sounds and drives. The packaging says it has an 11 out of 10 rating for quick repulsion, 10 out of 10 for hitting sound and control. It comes in yellow and white colours. The string is smooth with little grip, similar to the Yonex Aerosonic. It feels medium-hard and metallic, similar to the Nanogy 98. However, it is not as forgiving as the 66 Ultimax and not as durable as the Exbolt 63. Overall, Yonex has done a good job in striking a balance between feeling and durability.
