Its not a materials or general build difference, its build process. The way its done overseas is really just better than most if not all the factories here. NeverSummer might stay rideable for a very long time, but something like Ride, K2, or Echelon is going to feel like day 10 longer than a NeverSummer. And you absolutely pay to get that eagle logo on your board.
Thats pretty interesting. I would've thought that NS' high quality fiberglass layups would've played a positive role in preserving the pop and camber profiles of their boards.
