Sorry...can't really help you out here, just throwing out my thoughts. I'm currently in the process of having a custom Ti Seven bike built for me and I went with Chris King (guess I drank the koolaid
...because I was looking specifically for a colored hub. However, I've heard that the White Industries hubs are excellent as well. Hubs are designed to run both Shimano/SRAM, so I don't see what the hang-up is using a Shimano hub (other than your no brand-mixing criteria). But a good place to see the topic of hubs hashed around a lot, is on the "Wheels & Tires" forum at the Roadbikereview forums. Perhaps go have a look there, and see what some of the boys are running.
