the reason (I was told at the time) the pro teams abandoned deltas was cos mechanics hated them - after all they were very fiddly to install a cable. Campag even gave you a special 3.5 mm allen key for the clamping grubscrew. I loved Deltas - they almost had an ABS feel, never locked the wheel but had tremendous stopping power. What I wasnt to keen on was the brake lever that was able to run cables through the bar tape or externally. To run concealed cables, the inner wire had to bend over a pivot to change the angle. This sharp bend would eventually cause the cable to snap when you least wanted it (as I found out on a hairpin in Majorca). The other fault was the strong springing in the calipers that would make your hands tired if you spent lengthy periods on the brakes.
