Both. Its my #1 rig for big gills. #10 fly hook with a gulp mini earthworm or live wigglers.

I let it hit bottom then shake the rod tip 3-4 times and pause keeping a tight line, then move the sinker 6"-12" and repeat. I typically use 1/16oz drop shot weights. If really windy or fishing deep water i will up it to a 1/8. Never used heavier.

For vertical i use the graph and watch the fish. Keep it above them and watch how they react.
