Your using the 7800 FD with your setup? If you used the 7700 it would be a better combonation. The chain wouldn't rub as much on the gears extremes.

No rubbing on either end of the cassette on either ring. Using the 7800 coz it was part of the groupo. I just swapped the cassette and chain.

I know of a few people running the 7800 chain on 7700 cassettes with no issues.

I don't get it. You said your using it because it was part of the gruppo? But your using 9 speed right? Then it isn't part of the gruppo, it's part of the FD is part of the 7700 gruppo. The FD isn't part of the gruppo based on the Crankset, it's based on the shifting parts of the drive train components, ecluding the crankset.

I got a deal on a 7800 group minus shifters (as it is for my TT bike) So I got 7800 brakes, all drivetrain, cranks and hubs. Swapped the hubs for some XTR hubs to build a 29er set of wheels. Swapped the cassette to a 9 speed abd bought a sram chain. Am considering swapping the brakes for the new zero gravity when there is some feedback on them

Wanted nine speed so i can swap wheels etc with my other bikes

Basically running Shimano 10 mixed with 9 doesn't work terribly well anyway!

I had 9 speed everything apart from 10 speed chainset, bb and rear mech. It worked fine when on the middle of the casette and you didn't change gear. It worked...but very badly. So pleased I have full 10 speed!

swap the wheels?

Is the 10 speed cassettee compatible with 9 speed hubs?

P.S There is a 554g difference (without hubs) between Ultegra and DA.

Yea, they just popped the new casette straight onto my Kysriums!

Yup.....sent my bike details to go on the Road Bike article section, no word yet though...
