Hi, I've been playing Badminton for about 6 months right now. I first played with a pretty bad Donnay Pro-One Graphite, and then upgraded slightly to the Pro Graphite 100. The latter has served me well, but I feel that it's time to move on. I've been looking at the Yonex muscle power and isometric racquets, and if anyone could give me some advice on a good purchase for a beginner / intermediate, that would be much appreciated. Also, any tips on stringing would be good. Thanks. P.S.: I'm looking for a racquet with a fair bit of power behind it more than the control.
