The known carp anglers do so well because they have good water craft, lots of time and bait and are fishing the best lakes in the country! Rigs are secondry when you get the most important things right! Location, time and effort! Simple
Imo for as long as you rely on the lead to hook the fish theres not any rig out there that can stop the carp from getting away with it. When stalking ill watch a fish pick up my hook bait and strike before the lead even moves and hook them nine times out of ten. If i dont strike and wait for the lead to hook the fish they spit the bait vout 9 times out of ten , then iver keep munching as if nothings happend or just mooch of! If you put bells and wistles on the rig it wont help it just clutters things up!
