I'm using Tiagra 4503 shifters.

That would agree with my hypothesis. I'm suggesting that old Shimano MTB front derailleurs (though I don't know which ones) are compatible with new Shimano STI shifters.

That fits. If I understand Sheldon correctly, he's saying that ring size is the limiting factor for where a given derailleur will work with a given crankset and cable pull determines the compatibility between derailleur and shifters. So, a big chain ring crankset on a MTB should work with road derailleurs (though it shouldn't work well with new MTB derailleurs).

Natually, everything is easier with a double ring set up.
