What's a more offensive racket than AT900P? For singles and then another for doubles. Must be 3u, preferably yonex but open to other suggestions. DO NOT RECOMMEND AT700 OLD. I personally THINK that old and new should be the same with different colours. But some people say its heavier and more sluggish. I like AT700 OLD, not sure if I should take a risk to get AT700 NEW to upgrade for power.
Arcsaber Z slash, Ti-10 (if you can find one) or (sorry about this) an AT700. You could also add some lead or athletic tape to your AT900P.
SOTX Diamond Fighter 600 is more stiff, longer, more balanced, but packs a huge punch. IMO, better than the AT700 old.
If you think of the AT700 as a whippy racquet, the D-600 is stiffer and feels more explosive, as opposed to a heavy sledgehammer. It's also feels lighter, so I gain power (or at least maintain it) while gaining better defense. It also looks pretty cool!
I totally agree with above poster. The D-600 is an amazing racket. Very powerful. On a side note, you can give the Victor Brave Sword 08 a try, it's a pretty good power racket.
