Having ridden a few different combinations I would also say check out Campagnolo Bora's....without doubt the nicest wheels I have ridden. Pricey, but very very fast and light....and very reliable. Campag wheels now have HG hubs meaning they are Shimano compatible as well. I have had a few issues with Zipp's (especially build quality on the 404s)...but the 202s look nice. The Reynolds are also very nice and ride great and would lean to them over the Zipps. You could also go completely over the top and track down a pair of ADA's www.ada.prorider.org .....but then you need a second mortgage...but damn they are amazing
