The rig depends on the size of the lake, on the size of the carp and it depends on how you want to fish. you can use thin line and small waglers to get a real kick out of the drill or you can use something stronger if the size of the fishes is good and you don't feel all that confident on the thin line. the rig itself is preferabil to keep it simple. Any complications in the making of the rig would only complicate your fishing. so use the basic. i've used simple rigs and super special ones and the only difference was in the rig and not in the size or number of fishes.
Hope i've been of some help. Good fishing !
