this is something that takes some time to learn and it still don't work 100% of the time,  but when it does it is a deadly way to hit the holes.

First and fore most you must be able to pick out the cut banks and rock ledges, these are along the sides of the river where the current is sweeping by fast and causing a riffle or eddy where the current slacks at the mouth of the structure, this will cause a slack area behind the structure, using a sinker lighter than 6 ozs. will work most of the time but don't go too light, 3's and 4's are the ones I use for this. I also sometimes put a long thin crappie float on the leader line to help float the rig into the hole


second you must remember the fish will be laying in the hole to best suit the fish, meaning where the current is least but next to a spot where the current will cause bait fish to wash into the slack area. normaly this is where the structure meets the current on the outter most edge, Mr Wiskers will be laied up just inside the edge of this area,

Thire, you don't want the bait to go too deep in the hole or you might miss the target fish and catch some smaller fish deeper in the slack water.


Now when setting a hole like this you must keep the boat to the river side of the hole and up current a little and cast on a slight angle to the side, if you sit up river of the current brake then the bait will tend to stay behind the boat and not go into the hole, when casting try to hit the swirl in the water that is closest to the end and down river of the structure, this will allow the power of the current to "sweep" the bait into the mouth of the hole. the other reason to be off set to the river side is a lot of debris makes it to this same sweet spot, (that is one reason it so good a spot) and you don't want your line to go across this stuff but around it. Just imangine a foot ball player running a reverce "J" pattern to catch a pass, he goes down field then at the last second he turns and goes up field a few steps to catch the pass, same here, you want the bait to go down past the hole a little then be swept back around the end of the structure and into the hole.


well that is the low down on this tip, it is best practiced where there are little debris as you will loose alot of rigs till you figgure out the sweep and lay of the baits related to te current swirl.
