It's a question of how you feel comfortable using it. I lay mine on the water during certain situation and that is/was how I was taught to use it. There are different situations where it can be used either way. It's mainly up to you. If I told you that I used it X way during X situation another angler might say, I fish it X way under those same conditions. They might even use an entirely different technique. When I instruct people on this type of fishing I fish that way that I think it should be fished based on experience. Sometimes, that does mean floating the sighter. So my answer is that both people are right. Try it both ways and see what you like. This is where a trip or clinic would save you days of experimenting.
