I know people that have played with them in the past with some success (bottombouncer will hopefully chime in), but it is hard to beat a simple hair rig with a bait holder hook. A hair rig leaves the hook completely exposed so the sinker can set the hook when the fish picks up and runs with the bait. After you cast out loosen your drag so that the fish can run with the bait without pulling your rod in. Then wait for the drag to sing, pickup the rod and carefully tighten the drag.
If you want to learn more strategies for catching carp you should consider dropping by Osprey Lake on Saturday. Several of Ohio's most dedicated carp angler's will be there and they are always willing to share with other interested fisherman.
