Try Red prior to your build. If u ike it go wth that. It looks better, shifts better than 7900, weighs less, and is significantly cheaper.
I "upgraded" from 6600 Ultegra SL to 6700 Ultegra and the shifting is significantly poorer. On the weekend I re-cabled the bike to try to improve shift feel and quality (Gore cables, lubed all the cable ends, routed the gear cables straight out from the shifters and around the back of the bar) and it made only a marginal improvement. By comparison the shifting on my exposed cable 105 commuter bike is much better and crisper!
On the plus side the brakes are fantastic compared to 6600!
Did I mention the bulk of the shifter body and length of the lever throw? Not one for stubby and small hands like mine!
My mate has he same bike as me with SRAM Red and I'm definitley going to try it out for an extended test ride. Shimano seem to have gone backwards of late overall.

I have Ultegra 6700 on one bike and the shifting is fine. No difference on rear shifting compared to Shimano 105 5600 and front shifting is decidedly better. Did you use the PTFE cables?

What groupo was Andy Schleck using in the TDF when his chain slipped?

I do know of a guy I ride with occasionally with Sram Force dropping his chain a few times. There are also a few reports floating about concerning the durability of Sram groupsets. Light and cheap comes at a price.

glad to hear im not the only one... altho the S3s have a very protracted internal cabling system that adds to the problems.... altho after dropping spacers out from under my bars, i do need to trim them somewhat....
in terms of the exposed shifter internals i was mentioning in my original post, heres a pic, showing what rubs blisters on my middle finger if i am not wearing gloves.

Dr_Mutley. That gear cable path is asking for trouble. I'm amazed it's designed that way.

Why is that asking for trouble?

Doesn't the gear cable have to take quite a sharp bend from the vertical it enters the top tube?

So the problem comes from the bend required to enter the top tube vertically coming from the bars. Is that why quite a few use Nokon cable outers?

I am very happy with my Sram Red gear. It does run quieter with a dura ace cassette and chain though.

I have dura ace 7800 on ma bike, i love it alot but i am sure sram red will offer the same amount of pleasure, when it gets to that price, you can't go wrong. I do find that cassette choice and chain can make a large difference to the noise, but i am happy with my dura ace cassete noise.

My SRAM Red is starting to drop the chain occasionally on the crankset and the shifting doesn't seem so crisp anymore, but then, the cables havent been changed in 2 years
Just waiting for my bartape to arrive then it's replacement time! Otherwise, I love my SRAM Red.

I believe campy cables have a 3 year warranty
