Volkl Power Fiber Pro

It is designed to mimic the soft, responsive feel of natural gut while offering significantly better durability. While it won't perfectly replicate the unique elasticity of gut, it provides a very similar playing experience at a more accessible price point.

While it is more durable than many standard multifilaments, it is not a dedicated polyester 'poly' string designed for extreme durability. If you are a heavy topspin hitter who breaks strings in a few hours, you might find this wears down faster than a co-poly, though it will be much easier on your arm.

Yes, as a multifilament string, it is significantly softer and more forgiving on the arm than stiffer polyester strings. It is an excellent choice if you are looking to reduce vibration and prevent tennis elbow while maintaining good control.

The 1.30 mm gauge is a standard thickness that strikes a balance between playability and longevity. It is thin enough to provide excellent feel and touch, but thick enough to hold tension well and resist premature snapping.

No, one of the standout features of the Power Fiber Pro is its excellent tension maintenance. It is engineered to keep its playing characteristics consistent for a longer period, meaning you won't feel the string bed go 'dead' as quickly as you might with other multifilaments.

Absolutely. Many players pair this string with a stiffer polyester in the mains to add comfort and power to a control-oriented setup. Using it in the crosses is a great way to soften up a harsh string bed.
