So you're saying paired-spoke design = not equal spacing all the way around?
Where's [MENTION=55787]tsl[/MENTION]? He commutes on a Portland and might have advice/experience -- I don't remember if his is as old as 2007 though...
OP, that $198 for a set is sounding better (especially if you drop that to maybe $120 for just a rear as noglider suggested). I would pay an additional $20-40 for a local wheelbuilder to go over it and make sure it's tensioned as well as possible.
