A good racket is the one that u will like to use. What is wrong w/ yr titanium dream? Or what is lacking of it? If there is something u need that is not in yr current racket then you can start looking for another racket that has the characteristics that you want/need. Just remember, the racket is only 10-20% of yr game, what counts is yr stamina, footwork n skill to play well. You need more power, find a head heavy racket but make sure yr wrist, arm n shoulder can handle it. You need speed, quick swings frm a headlight racket you will lose power in hard smashes from the rear of the court. There are always compromises, just work out yr priorities then you can choose wisely what yr next racket should be.
Generally, the terminology of "good or best" racket is very subjective and no brand can claim that their product is better than the other brand. Since the style of play and physical attributes is different from one individual to another, a good racket from whatever brand held in other player hand would not necessary can become a good racket used in your hand. Therefore you must understand first your style of play and then blend that understanding with the correct selection of racket from all the brand out there (be it cheap or not, Yonex or not, clone or not) with the specification that meets your criteria. Then this will be a good racket for you. Since no racket by itself will do any millisecond amount of time your smashes, clear etc and since you, yourself at the end will do all the hard work for all of your smashes, clears etc, its vital for you to select the ideal racket that has all the specifications that meets specifically with your requirement.
