The blade is also equipped with state-of-the-art technology. The JF-90 blade was used exclusively in the predecessor model, the FT3 Pro, and was a resounding success. The dampened core provides excellent control and responsiveness, while the reinforced edges significantly increase durability. The feather-light design, combined with Skeleton+ technology, offers players an incredibly balanced racket that feels lighter than 415 grams. Like the entire series, the JetSpeed Hybrid Kick Point is very popular with both professionals and amateurs. The reason is simple: versatility in the shot.
