I've had this generation of FD on a lot of bikes, usually 6800. The trick in this video was key to me being able to set them up: using an allen key to hold the derailleur in the big ring position before attaching the cable makes it super easy to get enough tension.

I like the extra tire clearance on the current generation (R9100/8000/7000) of FDs, but they are even more fiddly to set up. The built in barrel adjuster was hailed as a big improvement, but it has almost no range, so it's not really worth that much. I still need an inline adjuster to get enough tension on my frame with no brazed on adjuster.
