I am running Fulcrum 7's on my Focus Cayo at the moment but am swapping over to Fulcrum 5's quite soon. I used the 5's for a couple of journeys when I first bought them and found them a good ride - and they look good. there are some good deals on these at the moment. You can pick them up for under £150 if you look around. There are a couple of new sets on
EBay at the moment which you might be able to pick up cheaper. If you have been happy with the 7's why not look at the 5's?
