I prefer SRAM's 2 lever shifting over any 4 lever system. It works great with winter gloves on.

There's no FD trimming needed with the SRAM yaw FD.

I'm not sure that an R12 frame can even be set up for mechanical shifting. I think the holes near the FD are for Di2 wires, not a FD cable. Using SRAM, I put some clear bike saver tape across both holes to keep water out. Mechanical shifting isn't likely to work well with all the bends required with integrated bar/stems.
