I cant get my avid short 4's to stop squealling (front only), and ive heard a lot of good things about "mini" v brakes like the tektro RX5. Are there any negatives to it? I would need to use it with drop brifter style levers (9 sp dura ace). Also, whats some good mini V's to look at on the budget? I only need one as my back canti works awesome (locks the wheel just fine, zero squeaking).
