in rivers i nose hook more it has a really natural sway of the river while when wacky rigging it looks kindof unnatural IMO i prefer nose hooking them and by heavy weight i use 1/2-3/4oz for the single purpose of letting the bait sit stationary and get that nice natural river sway... with some worms it even has a paddling action if it had a spade shaped tail from the current and it looks like a small baitfish fighting to stay stationary, it has worked incredible at cleaning out bedrock riffles where its 10-15' deep and you can pull honestly 25-50 fish out of the deep bedrock riffles the size of a car! ultimate finesse i dont shake the worm i just let it sink on a tight line making sure my angle is correct to the line doest drift with the current and i have a solid line from my rod tip to my weight, and wait for it to load up, i like using translucent baitfish colors in rivers most, i use this mostly in clearwater in stained i used crankbaits and stuff more but i dont fish rivers much so i havent had much time to experiment.
