I want to run the blue carlon flex tube to all my TV locations from the media closet. It's new construction and will run inside 2"x4" walls. The 1" stuff looks a little too small and the shop I will be buying from didn't have the 1-1/4" or 1-1/2" tubes. They did have 2" but it looks like overkill and I don't want to chop up my top plates that much. So what size do you guys run?
