Yonex Poly Tour Fire Tennis String — 16L (1.25mm) Yonex Poly Tour Fire is a round co-polyester monofilament built for players with long, fast groundstrokes who want firm, high-control performance with a slightly dampened impact that softens the harsh edge of maximum-stiffness polys. Its formulation sits in the firm-to-very-firm polyester range while using a construction that absorbs some vibration at contact — producing a crisp, authoritative ball flight without the punishing shock transmission of the stiffest control strings. Firm Round Co-Poly for High-Level Control — Poly Tour Fire is designed around a round profile and a high-density compound that delivers excellent directional control and predictable ball placement for players who swing with intent. The low elasticity keeps the ball on a tight, controlled trajectory — particularly effective on fast flat drives, heavy approach shots, and serve-return situations where precision matters as much as pace. Nicely Dampened Impact Despite High Stiffness — Despite sitting in the firm polyester category, Poly Tour Fire incorporates a construction element that reduces the sharp vibration transmission common in very stiff strings. This produces a contact feel that is crisp and direct without the jarring quality that makes some high-control polys uncomfortable over extended sessions — an important distinction for competitive players who use poly daily and accumulate arm stress across a long season. Impressive Tension Retention for the Category — Poly Tour Fire is known for holding tension exceptionally well among performance polyesters. Players who restring infrequently benefit from the extended window of consistent feel, and competitive players who string regularly can trust that the string performs the same way in practice on Monday as it does in a match on Saturday — a consistency advantage that firm, slow-losing polys provide over faster-decaying multifilaments. Above-Average Durability — The dense round monofilament resists notching and breakage well, providing solid string life for players who hit frequently or at high impact levels. Players who are chronic string-breakers with softer or thinner strings often find Poly Tour Fire delivers meaningfully longer string life — translating directly to lower restringing costs over the course of a competitive season. Ideal Player Profile — Competitive intermediate to advanced players (NTRP 4.0–6.0) with fast, full swing mechanics who want crisp, authoritative control and the confidence to flatten out groundstrokes under pressure. Best suited for players who value shot precision and tight ball flight over maximum spin production — flat hitters, big servers, and all-court players who rely on pace and placement will find Poly Tour Fire a dependable, high-performing choice. Specifications — 16L gauge (1.25mm), polyester monofilament. Recommended tension 44–54 lbs. String toward the lower end of the range for maximum comfort; mid range (48–52 lbs) for a balanced control-comfort compromise. Approximately 40 ft (12.2 m) per set. Poly Tour Fire works well in Yonex VCORE and PERCEPT frames, where the combination of a firm string and a stiff-to-neutral frame produces exactly the precise, authoritative ball flight that competitive-level baseliners and all-court players depend on in match play.
