Offering slightly more spin potential than the 16 gauge version, TNT2 17 has exceptional playability for a solid core string. This is partly because of Gamma's patented TNT2 processing which greatly improves the string's ability to store and return energy. The result is a lively string that does not skimp on control or comfort. Made with an Elastalon center core, outer wraps and a pearl coating to enhance durability. Excellent feel with a wonderfully crisp response.
