George started us on a good topic.  Building an airplane is an expensive and labor intensive process.  I've made many decisions where I didn't really like something, but liked the prospect of the time and expense to change it even less.  Those things don't tend to get as much coverage in discussions as what was actually done, even though there is a real lesson in what the person who just did something wishes they'd done differently.

This thread could be renamed "What I'd done differently"

Another good one would be "What I'd do again"
