The new Tourna Quasi-Gut Armor 17G string is an excellent choice for players who need comfortable string with great feel as well as those searching for something to hybrid polyester with. The string uses a high tenacity center core with DuPont nylon center wraps. This core is then wrapped with thousands of micro fibers. The USRSA rates this construction 2nd overall for comfort in play tests, finishing only behind natural gut. The core and wraps also yield impressive touch and feel, scoring a 3rd place overall finish in USRSA testing. Polyester wraps are then incorporated into the outer layer. These wraps vastly improve durability and delay breakage from stiff poly strings digging in during hybrid use. The 17 gauge diameter offers maximum touch and feel with a potential slight reduction in durability. Tourna Quasi-Gut Armor 17G uses innovative materials and construction to provide impressive comfort, feel and solid durability. The result is an excellent string choice for comfort minded players as well as those in search of a string that can stand up to use in a hybrid with poly.
