Lake Trout in Open December Water

It's a cold December day and we're out with Bill drifting for Lake Trout. We're using the pre-tied T-Turn bait rig, the 20R model. The key is that you're going to want the sinker just touching the bottom, keeping the bait in the strike zone. The other key is if your sinker is not tickling the bottom, move up to a heavier one, and if your sinker is dragging the bottom, it's too heavy, lighten up a bit. Find the sweet spot.
