Tecnifibre NRG2

The NRG2 is widely considered one of the closest synthetic alternatives to natural gut. It mimics the soft, responsive feel and elasticity of gut, providing excellent comfort and power without the high maintenance and cost of the real thing.

This additive is designed to reduce friction between the string fibers. By minimizing internal abrasion, it significantly extends the life of the string and helps maintain its playability characteristics for longer than standard multifilaments.

Yes, it is an excellent option for players dealing with arm issues. Because it is a soft, multifilament string, it absorbs shock and vibration much better than stiffer polyester strings, making it much gentler on the arm.

The 16 gauge (1.32 mm) is a standard thickness that offers a balanced blend of durability and playability. It is slightly thicker than the 17 gauge version, meaning it will last a bit longer, though you sacrifice a small amount of the 'crisp' feel found in thinner gauges.

It performs beautifully as a full bed for players seeking maximum comfort and feel. However, many advanced players use it in a hybrid setup—pairing it with a stiffer polyester string in the mains—to add comfort and power to a control-oriented racquet.
