I've found having a larger rotor not only increases power but makes it much easier to modulate the power availabe, I can rolling endo much further, and i mean *much* further, with the larger rotor on. Being 8 stone just means you'll slow down even quicker you fool :-"
BUT, if you want a 180 rotor and it's for your freeride bike then surely the Aztec is the choice as they have been specifically designed around that type of riding (fairly lightweight, good cooling properties) whereas the V!Z rotor is designed for trials use (8 splines to stop it bending as easy)
They were EA30s what do you expect lol Ever heard of fatigue dan :deej:" Besides which I'm only 11 stone, I think I know who "needs" it :deej:
