A badminton racket buying guide for club players — explaining the three trade-offs that actually matter: head balance (head-heavy vs head-light vs even), weight class (2U through 6U, with 3U for singles attackers and 4U as the doubles default), and shaft flex (flexible for beginners, stiff only for fast swingers). With a simple buyer's framework matched to playing style, and the frank reason most club players are better off one notch lighter and more flexible than they think.
