Michael,
I used the "shallow knees" clueless used when I did my build 7 years ago. Made the pulling a lot easier- one of my runs (from the CR to the MR) is 4 pipes that have to go 35'.
I was so concerned about water (rain) and construction dust getting into my pipes that I bought those pre-fitted rubber caps that go over them, that you can tighten down with a screwdriver. Then I wrapped them with duct tape.
The construction guys picked at them on breaks, used them as cup holders, leaned on them, etc., so it was a good thing I erred on the side of caution.
Looks GREAT so far! Keep 'em coming- er, uh, after the inspector wakes up.
