See - here is what you do...you take your Campagnolo Cork Screw and a good bottle of wine.....

The "can't shift like Campy" argument with di2 is completely moot. I've ridden everything out there, and di2 is simply the best shifting system. Campy's electric is just as good, but a bit different. Their lever feel is better though. And you can adjust di2 on the fly while riding (though it is tricky....and seriously, why would you need to---once di2 is setup, you never, ever, ever have to touch it again).

Not my experience at all. A riding friend of mine has had his in ~2x year for adjustment because the bike starts to sound like a Huffy after 6 months

As for weight....I'm not going to worry about 50-100 grams. IF Campy had the same cassette spacing as Shimano/SRAM, then I would ride their derailleurs/levers, even if they weighed more. However, given that the current 10spd version of di2 is pretty tuneable, with the batteries rather easily transferable (or swap them out for aftermarket with 3x the life b/t charges) to be hidden in the seatpost, and the di3/11speed looking even easier to adapt, I just don't see a real world argument for Campy.

Plus their cranks & brakes are at best, 3rd/4th best overall.

We have two groupsets that work so well that aliens may have delivered the technology...there is less than 100grams between the two....so, we need to find some real areas of difference. A bottle opener and a belt buckle.
