It's true. I use Koolstops with mine, but a friend uses an RB lever with Evo mounts, Standard maggie booster, back pads, no tar and no grind and the brake works just as well as mine with, an RB Lever, 4 bolt mounts, Koolstops, RB Booster, small amount of tar an a very light grind. Don't know how he does it though!
