What are the hubs? Are you looking for new wheels? or planning to rebuild? I would likely go with Sun rims, the CR18 I think is what I put on my Hetchins. Just pain shiny silver rim, w/ eyelets of course. But alot of guys here like the fancy VO offerings.
Will you brakes reach the extra 4mm to a 700c rim? That would be the first thing to check out.
