Often I see conduit with a LB at the top and bottom run up the side of a house with vinyl siding and think it looks like a hack job.
If I need to run a line to the second floor and there is no other way (like a plumbing chase) to get there I remove some vinyl siding and cut out a small section of the sheeting and fish the line in the wall.
It's more work but there's no eyesore on the side of someone's house.
I'm also the guy that will only use wiremold when there is no other option.
