I think I've owned it all as far as odd wheels:
Ti spokes (sold Jez his, missed them enough to get another wheelset built with them)
Wavy spokes (I mean, what was the point. None I could notice other than their fragility)
Fancy lacing (nice, but a little pointless)
Carbon spokes (see wavy spokes)
Bladed spokes (just don't put anything near a spinning wheel - one of the reasons I don't like them, they make me nervous)
