Upgrading Disc Rotors

Sikora

I have an '08 Rockhopper Pro with Avid Juicy 3's, which i just don't rate at all. I find they don't slow me down quick enough. They've had plenty of time to bed in too.

Will i notice much of a difference if i upgrade the front rotor to a 185mm?

Going from 160 to 185 will give you a corresponding increase in 'power'. But if your problem is contaminated pads, then you may still have the same problem.
