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 control and spin can be felt immediately. A string designed especially for topspin and tournament players who particularly value control and spin potential.
