Just to mix things up I put Bridgestone re050's on my motor last year. Not an RS I know, but a very torquey mondeo st tdci.
I find them really good, way better than the conti's and yoko's I've had in the past.
That's on damp country lanes too... Not brilliant on wear but that's probably 400lbs and my right foot to blame there...
Hope this helps...!
