I actually have two bikes with those exact setups in the other room. What do you know?

The 10-speed DI2 is very nice. I had it on two bikes. I still have the 10-speed Ultegra Di2 on one of the bikes.

On the other bike that had Di2 10 speed I just last week switched over to an 11-speed Ultegra setup. The reason was that I needed to get a lower gear for some of the hills I ride. The 11speed setup gives me a 50/34 compact crank with an 11/32 cassette. The 11/32 is basically the same as the 11/28 10-speed cassette I was using before, but with the extra 32-tooth cog. So the spacing and gear selection is similar to what I'm used to except I have that one extra low gear.

I miss the electronic a little, but not as much as you might think. I miss the auto-trim on the FD. FD shifting is fine, but not butter smooth like the electronic. The RD shifting is about the same except you have to push the lever a little farther. I can still shift both derailleurs from the drops.

I could have paid the extra money for the electronic 11-speed Ultegra, since it also will handle the 11/32 cassette, but I'm not missing it too much (yet anyway.)
