Michelin Primacy every time for me. (currently got the new Primacy HP's on)
They DO cost more but...
Last far far longer than anything else and are quiet. They give me enough grip as well (I do test the grip a lot :firedevil by the way !) however they'll never be as good as sticky F1's.... but they'll last three times longer.
Also in the camp of only buying two at a time as well and see no point in rotating unless you have a 4motion in which case you should.
