RS New York multifilament tennis string is the ultimate multifilament string developed by Robin Söderling together with Japanese engineers. RS New York is as close as you can get to a Natural Gut string when it comes to feel. We believe that Robin has nailed developing the world's best multifilament string and we recommend using the string in a hybrid string bed. That will provide the ultimate soft feel with large touch and spin potential while playing with a Natural Gut feel for a lower cost! RS New York is available in 16 or 17 gauge (1.30mm or 1.24mm).
