Interesting. That site has the first broken TA and Sugino Mighty cranks I've ever seen. Campy has the reputation, especially on cranks that have been milled or otherwise had material removed. QC has improved tons over the years--I know this ain't PC, but if you had 100 NOS sets of Stronglight 63 cranks and 100 sets of new Ultegra cranks, the STronglight pile would have many more times the breakages out of the same number of miles ridden. The "sameness" in appearance of some modern load-bearing parts must certainly come from trying to design the stress risers out.
A mechanic's guess
