Dear friends, i've been playing for 5 odd year and using light weights all the way (my current is evo 3 from prince). I wana experiment with something headheavy and have tried N90 but boy did my speed (n my wrist, arms ,shoulder..u get the point) suffer. I'm a hard hitting doubles player but love a bit of deception here and there. Checked out N77 and N55. Do u think is suitable for me? and any other recommendations? thanks!
