I noticed the northstar, protostar, trigger, grind machine, and other plastics with spacers all are loud, no matter what bearing you put in them. My shaqlerstar is still somewhat loud even with a generously lubed 10 ball! I was wondering if anyone knew the acual physics about this. THANKS!
From experience, the Protostar is one of the more quiet plastic yoyos.
Or maybe it’s because the one I have is the super-smooth original run.
