bass

Most lines that sink will work their way into the softer top layers of silt, weed or whatever chod you are fishing over and the pop up will look to a carp from above as if it is sitting onto of the silt ect. Use a light lead and it will not sink into the silt too much. My point is the chod hooklink length needs to varied on how deep you want it off the bottom, the length from the rig to the lead is set a over the silt depth as not to drag it into the bottom as the lead lands

I have found that 1 to 3 inches works well depending on the type of bottom I am fishing on, the deeper the silt, the longer the chod, also if you are not using leadcore have a look at the new avid chod beads, great product.
