Victor Jetspeed s12 ii is a slightly head heavier version of the 90s. Nanoflare 800 is a quicker version Auraspeed 70k C has similar flex and also head heavier but still having the sword frame
I really recommend the Yonex Nanoflare 800. You can find my review floating around in the forums here.
+1 the nf800. Never had the 90s but from what others have said about it, the nf800 will be stiffer, and the head is smaller as well. So keep that in my mind if that isn't your cup of tea. The 90k could be an alternative if what you're looking for is more power at the cost of some speed, though still plenty fast enough owing to the sword frame. Sent from my Pixel 4a using Tapatalk
