Having tried the BS10 and Auraspeed 70K, I’d say try either the old Auraspeed 70K with the blue and orange color, or the Auraspeed 98K. From my experience, the auraspeed line has slightly more hold and a bigger sweetspot/head than the bravesword line, but it’s as close as it gets. In fact, it currently has the most compact head feel from the various racket lines I’ve tried from Victor. I’d recommend the JS10 too, but it has too much of a durability issue for me to recommend. I don’t recommend anything from the Hypernano, Drive, Thruster series either - they all just feel too different. I don’t recommend anything from the Yonex line up, besides MAYBE the Nanoflare 800, but I’m only going by specs and not from experience playing. Everything else from Yonex is way too bulky, or has too much hold feel in the frame.
I agree that the auraspeed range is closest to bravesword. Jetspeed 10 is too head light to replace bs10. Maybe as90k, as70k or as98k would be most suitable. I used to use BS11 and BSLHI and haven't found a direct replacement. Maybe try to find a few bs10 if you can, they sometimes come up for sale.
