I'm guessing that: Smash power: bs>sp Speed: sp>bs Defence: sp>bs Control : bs>sp Netplay: sp>bs Did I get it right? *the one on the right of this(>) is better in the aspect.
Smash power: bs>sp (for the bs10, a stiff shaft ) Speed: bs>sp (sword frame) Defense/netplay (also because of speed): bs>sp Control: bs>sp ^sorry, just being random, I never tried Spira rackets (I only have a Brave Sword 10) but the bs series SHOULD be the fastest victor rackets due to the Brave Sword frame.
ive never tried the BS 10, but personnaly i think the spira 21 is pretty powerful and smashing is very decent, better than VT 70 IMO. Speedwise the spira is very good you almost dont feel the head heaviness, control is nice as it has a very stiff shaft.
spira are better in power but a little bit lack of speed if compared with bravesword . i've tried them before
IMO BS10 is better than SP22 in all aspects. I owned both but sold the SP22 to a friend. Control: BS10 > SP22 because of the superstiff shaft Speed: BS10 > SP22 because of the Sword profile Defense: BS10 > SP22 because of the profile Power: BS10 > SP22 due the superstiff shaft I would skip the SP22 and would go for the BS10. It's one of the best rackets ever made.
