Also, 6700/5700 have a tendency to break the shift cables inside the shifter body. I have 5700 and I've had this happen 3 times now, so about once every 7,000 miles or so. It's not too hard to fix, but it's still one additional issue that the older 7800 levers don't have any trouble with.
This is an issue common to 7800 shifters as well. They force the cable into a sharp bend at the cable head where eventually it can fray and then separate.
