Recommended badminton racket for intermediate players under ₹3000?
I've been playing badminton regularly for about 2 years now, mostly doubles. I use a Yonex Nanoray Light 18i which I got for ₹1200 when I started. My game has improved a lot and I feel the racket is limiting me now – smashes feel weak and clears don't reach the back. I want to upgrade to something under ₹3000. I play an aggressive game with lots of smashes. Head-heavy rackets appeal to me but I'm open to suggestions. Which racket and string tension would you recommend for someone at intermediate level?
