I am embarking on a big project, and since I basically have the summer off from work, I have a lot of time to work on my HT. My dedicated room is a 2nd story bonus room. I will be running cable in walls and under floorboards for the first time. I'll be using basic Proflex 14/4 cable, jacketed. My surround dipoles are wall mounted (not in-wall, just mounted to the wall. For the surrounds, I will have to go under the floor and up inside the walls to get to the speakers. Do I use a fish tape or push/pull rod of some sort to grab the cable from under the floor and pull it up inside the wall? How big of a hole do I cut into the drywall to be patched up later? Thanks for any help you can provide.
