AUTOMATIC strength?

[Tom Mandera <tsm1@domain.elided>]

I seem to recall hearing of some issues about the AUTOMATIC and 
LOCK-O-MATIC hub strength (Howard points out he blew one in a slightly 
wet lawn).

Is there a strength issue to be concerned about vs. "standard" manual 
hubs?  I recall reading the LOCK-O-Matic (I have the earlier AUTOMATIC) 
hubs got a design change mid-run to a stronger assembly.

Any differences in strength between the AUTO mode and the LOCK mode?
