Pro Red Code Strings
The most durable string from the Tecnifibre string range is definitely the Pro Red Code. It's available also with a wax surface treatment that allows the string to come back to its initial position and therefore increases the spin.
Tecnifibre Pro Red Code 1.25/17 String
Slightly livelier than the 16 gauge version, but still very much a control oriented string. Offers excellent ball bite and spin potential.
Tecnifibre Pro Red Code 1.30/16 String
Offering a crisp and solid feel, this co-poly monofilament offers excellent ball bite for control and spin. Red Code also offers impressive durability.
