I've never gotten a Cyclone FD to index a triple STI. May be my lack of skill. Last time I tried it, I finally gave up and switched to a Shimano RX100, which worked immediately.
I've upgraded several vintage bikes to STI, but in each case, the project started with finding a smokin hot deal on an STI donor bike.
FTFY (the first line Bill, since I wouldn't say I was resourceful when I did it). I have actually gotten a first gen cyclone to index with triple STI, and I wouldn't recommend it, like Bill said grab a FD which is already compliant like an RX100 and you'll be just fine I think.
