Old timer showed me a trick for fishing wire through finished walls that actually works

Was struggling with a second floor bedroom install last week in Denver until a guy I met at supply house told me to use a 6ft piece of trim coil as a guide. Has anyone else tried using metal flashing to route wires through insulated walls?

Yeah that's a hard disagree from me. Metal flashing is sharp as hell and one wrong move and you're slicing through drywall paper or cutting your hands up. Plus it can kink and get stuck in insulation like a fishhook. I've done a lot of these jobs and a good fiberglass fish rod with a magnetic tip and some patience works way better. No way I'm trusting a piece of trim coil to not tear something up inside the wall.

Ha! Man, miles581 is out here acting like trim coil is a ninja star waiting to slice up his whole house. Dude, if you're handling metal flashing like you're juggling chainsaws, that's a you problem not a tool problem. I've used it plenty and yeah it can kink but so does my back when I'm fishing through a 40 year old blown in mess. I get it fiberglass rods are nice but sometimes you just grab what works and stop overthinking it. Next thing you'll tell me is I need a dedicated fish tape with a Bluetooth finder or something.
