I also have a "do anything" CX-type setup w/ Avid cantilevers on a bike I typically only ride road and packed dirt trails (at the moment, at least!). I found a new Stella Azzurra Bellagio carbon fork through the folks at the Serotta forum for a great deal and had my LBS install. It's been fabulous - no issues, just a smooth ride and a nice weight savings, and much better aesthetics in my view over say a "loud" Reynolds.... I really notice the difference on harsher pavement -- less noise/chatter -- and with turns there's a really nice, hard to describe, carving sensation...

I considered a Winwood when I first had my bike built, since there weren't any other choices remotely in my price range, but there were no reviews and it was a relatively new company then. I'm sure you can find more reviews out there now...
