When you are 'piece mill' fast is $$
It's a lot qicker to grab the end of wire and PULL
Same goes for PEX..........PULL
Boss "OK guys.....we have 14 units scheduled for today. Hit it!"
One worker to another "Bet we can get done by 1 O'clock"
When I had to get to a failed transfer switch (8 mos. old) I had to pull a false wall out of basement compartment. Behind that fake wall was where all the plumbing/electrical runs were. I spent several hours folded up in there redoing/re-routing.
Left that wall out....gained couple feet of extra space PLUS I can easily see every thing.
