Babolat Touch Tonic is Babolat's second line of natural gut string and is not gauge specific like their top line. Packages indicate only that the string is either over 1.35mm or under. Thicker is more durable, thinner more playable. An especially good choice if you are looking to hybridize with a polyester.

VS Touch 16 is Babolat's best natural gut and arguably the finest gut available on the planet. Natural gut has the longest playing life of any of the racquet strings so if you are not a string breaker this might actually prove to be a cost effective choice in spite of the price. Available in natural or black.
