I have the standard ones and agree they arent up to alot, since buying the z I have developed a right leg like a bodybuilder! (yep, servo and everything is ok)
In the past I have prevented squeal by grinding the edges off each pad braking lining and doing the old 'copper grease' thing on the back and each contact edge of the pad which works well without compromising braking or safety, only a short term measure though!
