Might be easier even if you don't have a nail gun. If you're good at nailing. I could nail a subfloor (with cement coated sinkers--I've gotten the impression that they are easier than galvanized) in a 3-step process--grab-nail-and-set, WHOMP WHOMP--guys I was working with were grab-and-set, WHOMP, grab-and-set, WHOMP. But among other things I think their starting the nail was a bit more active than mine. I hated to mash my fingers.
