I did mean the sub floor. You can use headless screws for first rows but you don't have to.
I think I'd prefer to nail to allow for expansion as my total long run is like 40 feet - but this does raise a question for me:
I am actually planning to start in the middle of the floor, close to an island (center staircase) that I want to wrap around. I was going to run a control line off of the perpendicular outside wall close to the start of the island because it is the longest wall (27 some feet)/straightest. The parallel walls are offset and obscured by a fireplace with two sliders - not very straight/square with the house. After the control line, or mid room starting line, I plan to run a few rows in each direction blind nailing them to make sure the run isn't thrown off by the force of the power nailer. I'll try/hope to match the rows when I get around the island - backup plan is to put in a threshold or custom router a few boards when the two runs meet around the island.
What are your thoughts of using headless screws in the middle of the floor on the first row on both sides (after I add the spline). That makes me concerned about expansion also, but would make for a bomber mid room starting point for nailing against. oh, installing maple in case that matters. I've heard that maple can be squirrely as the seasons change so I'd like to let it go where it wants to.
