    I tried this string in my Carboflex 130 at 22 pounds. Overall, I found the string to perform well for the first little while, but the string went dead relatively quickly. The slick surface gave me a lot of spin and bite on the ball, and even after almost 50 hours of use, the string showed no signs of wear. It would be very difficult to actually break the Challenge Slick. However, after about 5 hours, the elasticity of the string was diminished significantly and the string lost a degree of playability. For the first little while, the strings were awesome though.

    Even though the challenge Slick is an extruded polyamide, it plays a lot like a tennis poly string and I could only really recommend this string to somebody who hits the ball very hard and is willing to either change their string fairly often or play with dead string. If you’re looking for a soft or playable string, this is not for you.

    The colours are really cool! The purple and yellow string turned some heads.
