Rodney, what do you mean the Z-bend will wallow out the hole? If you mean they will wear the hole bigger, why would they do this anymore then a clevis or other type of connector? If you mean that Z-bends shouldn't be used on large scale or pattern or on other high load applications, then maybe I would agree. However, I won't agree that Z-bends arn't every bit as "Precsion" as any other type of connection, sorry!
