Mostly I fish over bait, and the best attractor I have found is dog food. It not only attracts carp, but buffalo and catfish to boot. You would think that the best fly would be one that looks like dog food. Not the case, my best fly is a white body with pronounced red head. It looks like the plastic grub worm you buy in the park store. Second best is a pearl color tied like the white and red grub fly. They work best on a #10 hook. I have even caught them on white 1/80oz maribo jigs. Largest carp to date is an 18lber, and largest buffalo is 22. Largest catfish is only 6 lb. By far the carp are the hardest fighting, longest running,and fastest out of the hole. The buffalo are the hardest to land, it takes a long time to wear a big one down. I like to put the bait in 4 to 5 foot of water as to be able to sight fish. It is not unusual to have 8 or 10 fish at a time.
