A wacky rigged sinko is a great tool for catching lmb. Frank, if it was me and not having much luck with one I would look into my fishing line. And look for a line with low visibility. A wacky rigged sinko is a hard lure to be out fished. Frank, based on your fishing reports at the lake, I would be surprised that you would not go through 3 to 5 bags of baits per fishing trip. Chunk it out there, let it fall a bit ( slow count to 3 or 6 or somewhere in between) and then twitch it by moving the rod tip a few inches by a quick jerk. Watch your line for movement and then set the hook. I use a #2 or #3 wide gap Owner hook or even larger if I want it to fall a little faster. Good luck.
