I run 50 lb power pro. Have for years. It's only 12 lb mono equivalent but closer to 20 lb mono than 30 lb power pro. The thinner the diameter, the deeper it will dive.
I don't have actual numbers to give for depths. I check the chart for the depth I want, then stop 10 to 20 feet short of what the chart says. 2 main things to remember. 1, it's called a dive curve. Because on a chart it's a curved line. Not straight. So you can't just go with percentage. 2, you always want to err on the side of shallow. Walleye feed straight ahead or up.
