Dic size aside, I went from a mark 1 Fourplay running a Maggy (Phat pads on both smooth and ground rims) to the Team full build with 180 Hope Trial Tech's front and rear and I much, much prefer the discs. They have everything- power, hold, modulation in all conditions and also add to the perceived smoothness of your riding because of the lack of noise. Pretty certain I wouldn't go back to a rear Maggy unless I absolutely had to.
