FWIW I would seriously look into the possibility of floating an engineered wood product if installing on a slab. The glue was that foul, and starting that first row when building backwards from the hallway and newly completed room in front of my first row was a total nightmare because the wood has to lift slightly in order for the interlocking parts to mate. Don't get me wrong - the end result is great, but it was total hell getting to it.
