Auraspeed 77f, 70f, HS comparisons

avatar m

I have the Auraspeed 90k 4u (old version), and Auraspeed 70k 3u (old version), they have around 4/5 stiffness, but for days when I’m tired or have shoulder pain, I’m looking for a new racket that plays like these two except with a flexible shaft of around 3/5

I’m currently looking at

-Auraspeed 77f 4U

-Auraspeed 70f 3u (old version)

-Auraspeed HS 4u

-Bravesword 12 blue 4u

For those who tried these rackets, can anyone tell me which of the 3 are suitable for my needs and which are not? I’m most concerned about the feel (want something with unmuted feedback like the 70k), with a wide sweetspot (around the size of the typical Auraspeed), and good repulsion (around the repulsion of typical Auraspeeds).

Thanks in advance
