Racket Suggestion

I'm 5 foot 5 inch at height, I say I'm quite swift n agile, I just love fast drive n jump smash, not necessarily great power, but I want sharp n speed, I currently use arc 8dx n VT3, as u see they r quite stiff racket and heavy headed (atleast for me), so my baseline stroke n rear court return isn't so good or inconsistent due to my small arm size n lack of power not to mention my defense too, my swing is late and sometimes helpless during defending but I still manage to return some smashes,I think lighter and less stiff but slightly headheavy racket will do for me ,I play more doubles than singles n I'm at the intermediate level, any suggestion? Pretty please....

P/S: I think I don't wanna use Yonex anymore..
