I have built my bike with an automatix, it took a lot of love to get it too shift at the perfect rpm. However now that it is dialed, it is incredibly smooth. Setup: 38t(34t if I don't sport for a while) front, 19t back, gear-up at 18kph. The 18kph is perfect for cycling with friends or going up a reasonable grade. I would recommend it if your really interested. However when mine fails, I'm installing a 8speed alfine hub(with the possiblity to upgrade to di2)
