Juicy 3s are great brakes. ignore what the nay sayers, err say.
There is an issue with the odd new avid brake. leaking levers, poorly bled.but these are easily remedied, as are all other problems. The hoses are also poor quality in my opinion, and should be replaced for more power and feel.
Im a bit tired of people saying one brake is better than another. 90% of the time its just cos they aint set up right, or maintained correctly. for sure some are easier to change pads, or set pad distance, or lever distance etc. But learn your brakes, or get a decent lbs, and most brakes are comparable.
