I just installed the SCS flooring. I got the precut because of the time it took to make a pattern for the 170 years ago. It’s pretty nice, but heavier than I wanted. For the 185 floor and baggage area it’s 10.9 pounds and I still want to add 1/8 or so insulation. My carpet weighed 6 pounds.

The fit of the precut was pretty good, but I probably will just cut it myself next time I do it.
