Great flooring. We put the 3.5" wide flooring in our residence and after living with it for a out a year we decided to put it in our cabin also. I decided that when we did our cabin I would use the wider 9" planks thinking it would be an easier install. There are plusses and minuses to both. The narrower flooring is easier to cut around door frames etc. simply because it won't have to go around both sides of the frame so it is easier to get a cleaner look. The end joints are much easier to push together simply because they are narrower. Of course you have about 3 times as many edges to join. I tried to use the same pull bar and standard nail hammer to close the ends of the 9" wide planks and this was pretty difficult. The pull bar gave out and bent fairly quickly. I bought a very heavy duty pull bar off Amazon and used it with my hand held sledgehammer and this worked a lot better and saved my arm tendons and joints. I also used a homemade tool that was a heavy weight on the end of a bar that had a hole in it that could slide around the strike block and I could pull it to close the ends instead of using the sledgehammer. I made this because it was hard to close the ends using the hammer because I was too close to the wall to strike effectively. Think of it like using a t-post driver instead of a sledgehammer for setting t-posts.
