Been on one job with sparky where he installed the system he desribes. After listening to what he had went through in the past, and looking how he came up with this method, I wouldn't do it any other way. I especially like the part where he tells the GC or whoever else is involved to take a hike(in so many words)if they argue with his method. Determination and experience prevails, who wants to crawl into a shit pit to fix anything.
