Yesterday I played and old Friendship Tender Ti 10 Racket. Head light, medium flex and with a slim frame. It suited very well. Normally i thought i need more head heavyness to generate power, but I felt (and saw) a very high speed (also for Smashs; the "light feeling" allows me to generate a fast arm rotation). What is your recommendation for a very fast/aerodynamic [but also powerful] and light racket? Nanospeed 9900? Bravesword 12? Or the new Nanoray range? Normally I dont like very stiff rackets, but I think with a slim frame in connection with a light feel like YY 9900 it feels more medium... I will check those kind of racket against a still fast but slightly head heavy racket like the BS11. Thank you!
