Chas Cook is the owner of Vaux French carp lake.  This is the 5th article in an excellent series which gives you instruction on how to construct a series of carp rigs he’s used to great effect for his carp fishing in France. You can read all the articles here.
Both of the following rigs have, once again, been used to great effect when fishing to open water marks using the bag and double foamed hook length, so that neither rig sinks into the silt.  They are particularly effective when fishing to far banks, islands and lily pads over lake bottoms of sand and gravel.  Takes result in drop backs on swingers and single beeps on buzzers as the carp leave the bank and islands on the reverse.  The weight of the lead rapidly transfers to the point of the hook; in these situations 12lb fluorocarbon mainline is used, 30lb low profile leaders and semi tight clutches – not bait runners.
Bottom baits are used when carp are feeding along the far banks, but in the summer when  temperatures are higher, they spend more time in the pads or on the surface under the trees along the far bank and so 40-60mm pop-ups are used on a chod set-up.  Zig rigs can also be used off both helicopter set-ups, fishing to variable depths of water wherever the carp are lying in the lake and using 30-50mm pop-ups apple core shaped.  The zigs are designed to put the rigs as close as possible to the basking carp;  even if they are not feeding, carp at rest will naturally try to take a pop-up if a zig drops close to them.
