As for extremes of what did and didn't work, I'd offer the following off the top of my head:
1911 & 1916 wet systems at SS White Building, 12 stories in downtown Phila with steam pump boosting city water with city steam- did internal inspection to investigate feasibility of re-using 3/4" lines in a condo conversion from mfg; clean as a whistle. We did use new heads :) 2001 installation of Allied galv sch 10 at an office building west shore of Harrisburg, wood truss attic dry systems; After 3 years in service, with nothing done to the system but install, hydro, air test, acceptance test, drain and place in initial service- no ITM whatsoever- pinhole leaks tripped the system a few times and we ripped it all out and replaced it 3 years after putting it in service. Analysis indicated it was NOT MIC and, after the system was completely replaced at no cost to the owner (and no reimbursement from mfr) the property owner asked us to not bid their addition. Just makes you wonder what would it take to make them happy? Shoulda told em "One Year Warranty, have a nice day" but we did what we thought was the right thing to do. Just can't make some people happy, I guess.

Now since we have the weekend to hash it over, how about the systems that didn't last.

When we changed the 3/4" pipe, the internal looked like new pipe. This had been a wet system, but was fed by river water. Go figure.
