actually i think Zipp has one of the better naming schemes for their wheelsets - or at least their rims (They don't do wheelset name changes when they do hub changes, which is probably pretty good since the rim is the most significant feature). They have a number designation that corresponds to depth and stays consistent even when they change the model (before they had changed the number, like from 440 to 404, or hadn't changed the number even when the model changed - like when 404s got dimpled). And then they have a model/shape designation (Firecrest, NSW) that's consistent across depths (454 NSW, 858 NSW).
