So far, so good, these have given me a very good 2000 autumn miles (6-15 deg C, some dry, mostly wet). These are very good in both the wet and dry, and from experience they'll grip pretty strong even when the road is cold. Though it feels as though these improve considerably as you get more heat into them.
These tyres will aquaplane if the appropriate conditions present themselves, especially if you try to push on through a road with even some standing water, though recovery was quick in the times this has happened to me. Probably not a good tyre for beginners due to this.
These are as noisy and as comfortable as the old CSC 6s on my car were, which is to say they're quite noisy and not that comfortable, but this is fair considering the performance on offer. On the motorway they're not bad, but not great.
I've lost about 2-3 MPG compared to the old CSC 6. A small, but measurable difference.
