I agree that the half-step plus granny is what works nicely on a triple. I have three bikes set up with a TA triple. The front derailleur must have a very flat outer cage to avoid hitting the arm. A relatively long cage is required for the small ring. In that sense the Simplex should be good. My bikes use a Campagnolo 980, a Suntour Compe-V and a Huret (Duopar?, the long caged one with the inner spring plate). Any CPSC shaped front cage is bad news.
