I tend to use two coticules when I am honing a razor from scratch. I set the bevel and make the blade basically shave ready with a large, fast 20x5cm LPB sitting on the bench top. I then do my finishing laps on a much slower La Verte, and because I like to do my finishing laps with the stone held in my hand, that one is smaller, 150x5cm. That system works best for me.
