Astrox 66. It's 4u, slightly head-heavy, and hi-flex on Yonex's scale. There's also the Astrox 55, which is 5u and medium-flex. For Victor, there's the ThrusterK Onigiri, and the new ThrusterK R.
I am strongly recommend tectonic 7. Yestarday I bought the second one. Flexible, good for defence and drives, easy clears and respectable smash. T7 provides very soft filing and has stable good control.
