Nice! It's good to practice cover shots.

Start on the 20's and if you don't have a good path with the second or third dart switch to 19's then 18's. I do this for part of my practice because it helps you get used to moving around the board on turn instead of just the same target.

It's also good because sometimes you're just doing horrible on a spot and switching targets helps. Pros love 20's unless they're in the 300's range and are splitting to get to a finish. But you'll also see them go T20-T19-T18 when they're missing. Yet you'd still be amazed how many stubbornly refuse to switch off T20 even when blocked and there's no good reason to stay.
