hi there!! I have the chance to buy the avid juicy 7 2005 cheaper than the avid juicy 5 2006, but I´m worried as Ive heard Avid juicy 7 had some issues involving noise & shuddering, but would you do?; have anybody tested both brakes and say sth. about them?? avid juicy 7 are like 20 bucks cheaper than avid juicy 5 2006 so I think its quite a great deal!!thank you for your opinions
