Hi guys Im currently using a Nanoray Z speed. In the past i have used bravesword 11 and voltric 7. I perform quite well with the Z speed, but i feels it lacks power in clears and feels a little awkward. I decided to buy a new racket so i need some recommendation from you guys and I'm more towards control rather than power and love stiff rackets
Arc11? It's even balanced and a good control racket. Like wise, it's able to generate more power as compared to the nanorays.
Victor MX 80 or MX 90 should then be on your list. BS series is toward even balanced but most of them feel quite flexible.
nanoray z speed has a pretty flexible shaft already. if you're having trouble with your clear shots, you might just want to practice and fine tune your form. hitting more clears in practice or have a 30min training session hitting clears. switching racket won't help much at all. first is to always check your swing and form before assuming it's a racket issue. what are the things you don't like about the z speed? what are the things you want from a new racket?
For your advanced level and control doubles play, ZSPD is too flexy and slow to react. Perhaps Arc11, or the new NR900...would be stiff enough. From Victor, consider 4U TK8000 or 9000, or MX90.
