The only way I have ever fished for cats is on the bottom with lead , ALWAYS trying to use enough lead to keep it where you threw the bait , NOW I hear the way to catch Biguns is by Trolling/drifting ?? Also hear that these folks use lead that comes in a peice of rope or a platic tubing ?? So where around Columbia can you buy this type of rig ? Also what size hooks do ya use ? Many Thanks Allen PS, if anybody has a pic they can post of the drift rig that would be MOST Hdelpful !!
