32 spokes on the back and 24 on the front are the minimums that I would recommend based upon doing a lot of reading.
I would suggest Colorado Cyclist except that I don't think they offer White Industries hubs.
I have White Industries because of buying used and getting them half priced. They are noisier than Shimanos.
If you want to purchase from CC, I would recommend a pair Mavic of CXP-33's or alternatively a DT Swiss 1.1 front with either a double eyelet 1.1 or 1.2 rear on Shimano Ultegra hubs. 24/32 spoke counts. The Shimanos are cheaper, quieter, will roll forever and last as long. In additon they are extremely easy to maintain. I have some Shimano 600 hubs on my backup bike and just recently realized how much I loved them when I had to ride it while my primary bike wheels were being repaired.That is what I would do if I were purchasing new over the internet.
I replaced the Aerohead O/C rear rim that came on my used build purchase with a Velocity Deep V because the White Industries 28-hole hub broke and the rim was developing small cracks around the eyelets. Even though I purchased it used WI replaced the LTA shell with an H2 shell. The Deep V is a great looking rim and matches the Aerohead front. If WI had no warranted the hub I was going to replace it with a 32-hole hub. I have been assured the Deep V with a 28 hole will hold up. I consulted the original builder before I purchased the used wheels and he thought I would be okay with a 28-hole O/C. Since then he has changed his Aerohead O/C builds to put less stress on the hubs and WI has beefed up their hubs. The O/C rim lasted reasonably long and was a great riding rim. But the Deep V rides well also.
Based upon looks and experience, I think my ultimate build would be a pair of Deep V's on Ultegra hubs.
The morale: Don't skimp on rim strength and spoke count if you are a Clydesdale like me.
