I have 1 wheelset built up with CR18s. They're good rims. I have 3 wheelsets built with Sun ME14A. Really good rims. I don't know if you can find them anymore. They are no longer listed on the Sun Ringle website.
I just built up a wheelset with Araya AR-713 rims. They appear to be really stout rims.
