I'm with blamp28 on this one. Decorative and odd lacing patterns are for show, not daily use. If you want to build a wheel set for occasional and special purpose use, go ahead but don't expect them to be as reliable and trouble free as a standard wheel.

Also, if you are going to have to rely on an LBS to maintain and true them, I think you are ill advised getting into this type of wheel. If you aren't comfortable enough to do your own work on them, stick with conventional lacing.
