I've always been a manual guy but I am now a total dual clutch box convert. My C2S is pdk and my M3 is DCT and no regrets whatsoever. They shift faster than you can plus I love the noises they make. I always use the paddles and never use auto modes on either car. I guess it's kinda like shifting masturbation in a way but whatever I find the dual clutch box just as engaging the same as I would rowing gears. Plus you can left foot brake on the track if that's your thing.
Im not going back anytime soon.
