I will probably have to replace every roof bracing stud. I plan to use hardwood studs there, not pine. For the walls, I know I will have to replace some of them. I hadn't thought of metal studs...ill give it a thought as I get into the walls. I've never used the metal studs before, but this might be a good place for them. Thanks for the idea.
Depending on where and how many wires need to be run, some conduit might be a good idea.
