@anap2400 i have ATLAS in the hallway; i'll have to take pics tomorrow when it's brighter. It looked good in the stairs, but the hallway the pattern was okay. the color is nice tho. If I could, I woulda went with White Oak for the whole top floor.

Thanks for the responses. The wood came from a mill in TN. I called and talked to the the company I ordered through and they sent me the NWFA installation guidelines, but didn't have any specific beyond that. The NWFA installation guidelines don't seem to get too specific on wide plank installs though. So it looks like I don't really have any mfg guidelines to be following here. G&S, you said use a roll on vapor retarder and then apply beads of glue directly onto the subfloor? How does that work? Are you putting the vapor retarder and then applying beads of glue on top of that, rather than the plywood subfloor? Or did I misread that and you meant skip the vapor retarder and apply beads directly to plywood subfloor and then nail? What vapor retarder do you use, and what glue for your beads? Thanks again for the thoughts. Jason

We do prefinished color matching over 1,000 square feet. Cost would run about $ 12.00 square foot 3/4 inch engineered. Character White Oak I presume. See more here

Your local wood flooring supply shops will have their go to MFG for wide planks. Start there, rather trying to source it yourself. They probably source from the mills mentioned above already. There are about 7 suppliers in my area. They all specialize in specific brands and products. I go to each one of them for different products and needs.
