The innovative TCS represents a breakthrough in string technology. This polyethylene string has been modified using Polyfibre's own, specially developed SMD technology to produce a surface resembling an orange skin. This provides hugely enhanced spin potential and the ball has a much longer dwell time on the string bed, making it easier to control strokes and play more precise angles. The mechanical incorporated structured surface provides the special grip of this string. The control and spin can be felt immediately. A string designed especially for topspin and tournament players who particularly value control and spin potential.
