The Bream Buster XF is about as good as you will find. As far as I know this is a fantastic rod for light bream work. Of course the downsides are the price and you might have difficulty finding one.
You might also be interested in The Bream Buster Ultra-Finesse as it is 1-3 kg not 1-4 kg and will probably be a bit better at casting lighter lures.
BTW, I actually haven't caught fish on the two rods but a lot of people say they are fantastic rods. Have a look at the Bream Master forums. These rods are very popular there.
