Recently did approx 1200 sq ft of our house with laminate wood flooring (Bamboo and Brazilian Cherry)
I knew that furniture and anything else that would be sitting directly on the floor would need to have some sort of felt padding applied, and that really did the trick as far as preventing scratching. Home Depot and the like have precut adhesive backed material in just about any size you would need. Makes moving the furniture around a breeze as well.
My other concern was the Pin and Juke I have. The Juke weighs as much or more than the pin and has a smaller footprint, and I was concerned as to how likely longterm placement would affect the flooring (indentations). It's only been 6 months, but so far so good.
I didn't have to deal with installing a sub floor, just a vapor barrier / pad, so I have no advice on that route, but the Dri-Core looks sweet from an installation point of view. Good luck with the project whichever route you go.
