One thing not mentioned is to expect a slight hop on most metal rims where it's joined; don't try to get the radial true perfect in that spot. You could start with a 20h, but it'll require a lot more tension, so you'd at least want some experience with truing first, it you're likely to round off nipples.
The real hard wheels have the paired spokes or triplet lacing. Or 16h, that's tough.
