I find I have to adjust our shiftmate cable about every 200 miles. It is a pain but I love the shape of Campy 10 shifters and the front shifting is great.
I have used both Campy and Shimano shifter and FDs and for us we can shift under much higher load with Campy shifters than with a Shimano shifter. This is with either FD installed. I have not tried SRAM shifters since they do not support a triple. Of course we try not to front shift under much load but sometimes it happens.....
