I've got Continental Sport Contact 3. They are really grippy in all conditions but they are pretty noisy and haven't lasted very long. The fronts have only done about 7K miles and need replacing.
Same on mine mate - just done a 600 mile round trip to Cornwall and the road noise was quite noticable. Don't know whether its because the fronts are getting a bit low, apart from that I have been pretty happy with them. Were fine in last years snow too.
