why 350 hz
why 350 hz i ask mainly cause most people cant pass 15,000 rpm acept akis and the new balls go up to 20,000 if we cant get past 15 most of us why would 20,000 benifit us i would rather have the heavy rotor for building your arm up to get high score with the 250 hz balls
Well for a start, 350Hz is actually 21000 rpm!
It's just a "badge" though, indicating what sort of speed COULD be possible. Akis can do over 270Hz with a 250Hz Powerball, but I'd be surprised if he can do 350Hz with the fast Metal.
At the moment the heavy rotor is all that's available, but the fast rotor will help those of us who are struggling to get past about 13500 to know what it feels like to get 14000, 15000 or perhaps 16000.
