I have not…but just nipping back to this thread, I went for the Zipp 303s in the end. Looked like a lot of positive feedback even at £985RRP so at the £750-odd I paid, seemed like a good deal. Largely attracted by the warranty from a company I would hope will be around long enough to honour it if needed. Suspect they will have a few rough edges and 1550g is not featherweight but hopefully CX Sprint spokes and hookless rims will take a bit of a battering without too many problems.
