I've only used 3x on polo wheels. I've got a crows foot on the back of my commuter bike, which seems to be incredibly strong,and was massively easy to lace. In theory it gives more lateral strength than 3x because of the radial spokes. If I were building my own 48h wheel, I'd try it on that (pattern needs to be divisible by four) and maybe interlace the radial spokes through the crossed spokes.
