Definatley the second set but then again i am a little bit biased. They are a bit of a pig to clean but well worth the effort. I use AG wheel cleaner then scub the join between the steel and the alloy with a brush. I take mine off every 3 months to give them a full clean and a coat of polish and wax. But they look loooovely when they are done.
Allan,mine look realy hard to keep clean but i gave them three coats of wax the paste type, mine was race glaze but any of that type have made it so easy i only use car shampoo that i use on the car.and the muck just washers off.
