Hello, I started badminton for fun this year, playing mainly doubles and occasionally singles. Without a coach, I relied on videos and online advice to improve. I'm good at movement, reflex shots, defense and midfield, but I struggle with basic shots. I can hit the baseline with a forehand if I'm fast, but my backhand is short. I use a light, flexible and maneuverable racquet, but I want one that is still flexible but top heavy with a weight of 4 or 3u, for extra core power without overworking. I plan to upgrade by January, as I play 4 hours a week for leisure. Recommendations ?

Whats is your actual racquet ? What is your budget ?

Maybe before changing racket, you can can change the string. Whats is your string ? Tension ?
