DSG is a great system, and can in 99% of situations give you full control over the box.
The only flaw in the system, is VW's refusal to programme it so that you can left foot brake at low speed, it's a small annoyance maybe to a handful of drivers, but if you always use 2 feet it will drive you mad when it refuses to pick up when you need it most, ie entering roundabouts etc, waiting for the gap, then suddenly finding that it's like the mother of all flatspots when you floor it. Apart from that gripe, it works perfect with left foot braking when the speeds are up higher and the engine is spinning, ie fast road blast, then I have to say it's a real laugh just getting the thing to dance up and down the box at will, faster than anyone can ever get a floorstick to change gear.
Compared to the jerky gremlins in an E36/E46 M3's SMG, I agree that dual clutches are probably the future of potent cars, as shown by the new Mitsi Evo, and forthcoming M3 dual clutch system. They will just get better and better.
