I doubt Mike's repair had a detrimental effect on the rest. More likely, whatever caused the first part to go, finally got the rest. We also don't know that Mike didn't recommend a better look or complete relay. All we know for certain is that the partial repair didn't solve the entire problem, so whatever was spent on the initial repair, was money down the drain. Sometimes we gamble, sometimes we lose when we do so.
All I'm saying is that an educated assessment is in order, especially when it concerns safety. A loose rib can be a sign of a safety related issue. Other than that, I don't really care if you run some 3/16th bolts through both ribs to hold them on.
