+1 for Conti Ultra Gatorskins from me.
Thousands of commuting miles (former office 22 miles away) and no probs.
They come in 700c x 23 size.
I too have ridden in very wet and slippery conditions on them and found them no more wayward than I'd expect a narrow, high-pressure tyre to be.
A road bike on 23s will never be an MTB on knobblies, but these work for me.
