Did you get this sorted out? Is the noise coming from shifting, or just pedaling? I find that if I set the height of the FD at their recommended height, when on the big ring and the larger cogs, the chain hits the little square tab of metal in the upper inner corner of the FD cage. This is more of an issue with a large chainring and a cassette with some large climbing cogs. So I have raised the FD up more and more to clear it, but then it's sorta high. But I think that is where your chain rub might be coming from.
