Any 'commercial style' water with plenty of carp in to 10lb or so would be a good water to start on, don't use too light a fly rod, 6-8lb leader will be fine for the above mentioned sizes, but if bigger are possible 10lb would be sensible. All manner of things can be used, from small bushy dry flys, actual flys tied from deer hair to imitate pellets are effective, 6mm cork balls, small pieces of coloured foam cut to look like a pellet. Feed little and often 6mm floating pellets (although sometimes you can find fish naturally feeding in the surface scum and target those, which is more pleasing)and wait for them to start rising. The beauty of using the fly rod is that you can lift off and target a taking fish far more easily than constantly reeling in a controller float for example.
