Thanks for the input John and Richie,
I will adjust my searches for clamp-on front derailleurs.
I had a braze-on added to my Carlton Reynolds 531 and never had any issues. I likely rode 1500 miles or more on that frame. Maybe the bad Shimano/Dura Ace and Campagnolo component issues that I experienced might have saved things from going really bad.
I know that the C-Record, Record and Super Record groups all had clamp-on front derailleurs available so I will look for them.
