Nice RRS, also good to see you were restrained in your choice of alloys, most you see have 21 inch or larger wheels, must do wonders for the ride.
Actually the only points you notice the difference is a low speeds and if the surface is bad, otherwise even the 21" are remarkably good. The main reason I stuck with the 20" was the road I live on is piss poor and they charge £1200 extra.
