Which Groupset?

Yep; when things get electronic the differences get even dumber .. DA stuff that is worth spending money on is brakes (esp if direct mount) and 9000 polymer cables

I read that the button feel was better on DA. But then read that 6870 has improved buttons in line With DA. So maybe the reviewer was on older Ultegra.

I Guess I'll just get 6870.

Best price for internal cabling/ internal battery 6870 gearset being Ribble no?

yep atm

I think all the shimano groups (above tiagra) come with the new polymer cabling.

Try Merlin too.

Would I be silly buying Di2 6770 and external wiring, with it being fairly old already?
I'm really not fussed about 11 speed (I'd have to replace my cassette, freehub, chain, probably complete wheel rebuild) but worried I'll be kicking myself in a few months time.

Nah its alright; not much gain apart from 1 extra cog and internal battery .. also depends on what price you are paying for it ..

I reckon I can get shifters, mechs, battery and cables for under £400 with some shopping around. Worth it?

I'd say yes. 6800 brakes are real improvement mainly for their clearance so opt for them if you can.

Great, just needed a bit of justification for spending! I'd leave the brakes as I'm trying to replace as little as poss, and fairly happy with the CNCs I've got

Di2 is great you will love it.

This was my upgrade list for 6770, it's the stuff like junction boxes and chargers that nudge it all up to £500

I also routed the battery into my saddlebag to try to limit the fugly of an external battery.

The cons column at the bottom is a joke, basically there are no cons really.

Cons? I can think of a few but I guess none of them are dealbreakers.

Yeah, there are a few, that were missed. But none are really cons, just possible slight annoyances to some people. As rim brakes can be annoying for some reasons.

It was more the cons they listed, are not cons in the slightest. Squeeling? Well bed them in right and that's not existant!

basically there are no cons really.

Very much this, you don't really see MTB brake column saying that the break-in period as a bad thing.

The only cons I can probably think of, is simply the larger learning curve of modulation the brakes, especially the rear which is ridiculously easy to lock up compare to the rim calipers brethren.

Organic pads a possibly con as I've worn mine out completely after 800 miles.

The biggest pro to me on that list is the extremely light touch, I often get tingling on my hand after a prolong period of using the brakes, but due to the light touch, I no longer get those as I don't have to feather the brakes a lots on a big descent, even in the Pyrenees, I arrived at the bottom with my hand feeling 100% perfect.

But then again, I do ride with massive tractor tyres...

I got 11 speed on the tourer now (bar end shifter on downtube bosses), just gotta wait for the R685 to be available, but right now I'm really enjoying the Hylex brakes.

Personal experience - the 8 speed Claris front derailleur is excellent with the 11 speed chains, basically I now have a extremely budget version of the SRAM Yaw due to it's wide cages, no more trimming.
