In my experience, Carp can be/are real skiddish eaters. They feel resistance, barbs, etc, they spit it out..
I have great luck fishing for em pretty much the excat way Jeremy does.
4-6 Treble hook, no weight, swivels, etc.. Just line to the hook.. Make sure you completly cover the hook...
I fish loose line with the button pushed, and jsut watch for my line to start running out, pick up the pole, click the button, let em tighten line, then set hook... Your in for a nice fight

..... Whenever I go to a local pay pond here, they have huge cat and carp (they stock em big), I always put at least 1 carp line for the fight.. alot of times, the cats aint biting but Im having a ball with the carp.. I can go there and regularly pull in Carp anywhere from 8# to 30#
