Finally ran a full home run through an attic in McKinney that had actual plywood walkways and zero blown insulation to wade through, took me 2 hours instead of the usual 6. Has anyone else ever gotten a job where the previous guy left a fish tape and pull string waiting for you?
A leftover fish tape is like finding money in an old coat pocket, and the plywood walkway thing cannot be overstated. If the last guy ran the string right, just tie on and go, don't overthink it.
