I had thousands of miles aboard Di2 drivetrain before I headed to Banff and I’ve never had issues with the electronics. I know that some are hesitant to make the leap to electronic shifting. Sure, it is expensive. But I've had far fewer issues with it than I have with cable actuated shifting. In the case of Di2, there are no cables that need replacing. It shifts consistently in all conditions and does so while also saving my wrists and fingers from the possibility of overuse injuries from the thousands of shifts one performs during Tour Divide.

I ran a 2x11 setup using an older 10-speed era XTR Race crank with 42/30 chainrings. On the back I used an XTR 11-40 cassette. I set the system up using Shimano's SynchroShift. I only told the system whether I wanted a harder or an easier gear and it would then shift the front and rear derailleurs according to a pattern that I customized using E-Tube software. So I could shift in both directions, across the drivetrain's entire range, using either hand. This is especially convenient while eating, drinking, or putting on clothes. I also added a set of shifter to my aerobars so that I could stay in them and shift without moving. The shifting is so good that I'm ruined. It's hard to go back to mechanical shifting of even the highest quality.
