I went from Ultegra 6700 to DA 9000. The difference is night and day, and if the new Ultegra is even close to the DA 9000, it'll be a major upgrade. The shifting on 6700 was really stiff, didn't like it at all. Especially the FD. There are a few online sellers I've seen that sell the new Ultegra for a very low price. So if you are thinking of buying 6700, compare prices to the new one. It's probably worth it to spend a little more for the new Ultegra.
