I live in South Carolina. The only pre-cut (93") studs you can buy are spruce. Robert (husband) has always used spruce in his constuction. Now we are building our new home. I bought 540ea 2x4x8' Yellow pine studs (at a great price) thinking these would be stronger, and we could cut them ourselves. Robert thinks they may bow in the walls. What do we do? Use the pine or buy the precut spruce?
