Currently I am playing with an Astrox 100zz. I feel like I want a little more speed in my racket, a little more faster speed and handling. Would I be better of with an Arcsaber 11 (pro?) or an Astrox 77? I DO need power also for my smashes since my smash is a little weak/soft.. (yes I know: technique;-) I play mainy singles and men's double... Thank you...
If you want power then go Astrox 77. But both Astrox 77 and Arc 11 pro wont help much in terms of speed and handling, IMO I've tried all rackets mentioned and 100ZZ got similar or better speed than both Arc 11 pro and Astrox 77. If you want both speed and some power, for yonex go 88S Pro (a step down in power but 1 step up in speed) and Victor got TK-F enhanced.
but victor rackets and yonex rackets have different frame shapes, be aware of it if you are sensitive about frame shapes
And be aware that the information around Victor rackets is bad and very confusing! As it is impossible to find the main differences between Thruster F Enhanced and the Thruster F Claw, and it might even be hard to spot the differences between the Thruster F and Thruster F Enhanced.
I bought an Arcsaber 11 pro recently and was not impressed. I've used some voltriks, an astrox 100zz and high-end nanorays and a nanoflare, with nanoflare 800 being my favourite currently. As for your smashes, racquets can make a difference, but the most improvement will come from your technique and timing (and string tension). Out of the two racquets you suggested, I would lean towards the Astrox77. But feel free to try li-ning, Victor and any other racquet after doing research.
